It’s been over 25 years since my Derby days. Watching this made me realize just how brilliant my old man was ...and how much I miss him now,too. He wasn’t the type of father to built the projects himself,that just wouldn’t fly with him! Instead,he’d stay right beside and guide me through each step,giving advice and tips along the way. Most importantly,he took the time to explain to me the reasoning behind HOW and WHY things worked the way they did. Consequently(no doubt intentionally) my old man instilled in me a lifelong curiosity in mechanics and engineering,which eventually lead me to a degree and career in Aerospace Engineering. Of all the random YT videos,it took this one to make me tear up and smile at the same time!
I came here to learn, not to feel
Why can't I "thumbs up" more than once?
i usually don't like comments like this but this was genuinely sad

My car was built like a DeSoto sedan and even had car doors. I came in last, but hey, I came in last with style.
holy smokes, should have put a spoiler and tint the windows. Would look nice.
My pine would derby gave out trophies for design as well.

We are having a race in S.T.E.A.M. and My whole class knows I have a secret but I won't tell anyone! I am taking as many notes from this video, and the other videos Mark put in the description, as I can. Also, my sister's car won for her grade so, I am taking some ideas from that car as well. I am also going to make it have the best paint job in the grade so that just in case I don't win for speed, I will still have a chance for design. I love science and art so this is the best project ever for me!

One of my friends always won the races for consecutive years in Cub Scouts. Years later I asked him how he always won. He told me that he (and his dad) put graphite on the axles which reduced friction. Great idea.
My daughter just won first place at her pinewood derby by using your techniques. Thanks Mark!!

We’ve done pinewood derby’s at family reunions in the past, we’ve done okay. This is the first year my daughter is doing it as a Scout. We’re going to be the Swiftest down the track.
I’m working with my daughter on her’s for powder puff. Not only must it go fast, it has to look like a prehistoric horse wearing a Girl Scout vest. And open to disclose yummy cookies.
My son’s middle school did CO2 cars and the science teacher had been unbeaten for 12 years. No graphite was allowed, so we just polished with a drill as shown. Our cars had axel holes drilled all the way through the body and so we also smoothed the inside of the hole with the smoothed axels. Anyway, he ( ok, we) beat the teacher for the first time. Lots of fun!

Beautiful work Mark. The visualization of energy using blocks is absolute genius.

"his 12 hour build against my 45 minute ex-nasa-engineer build"
lol
Well the physical build process may have been 45 minutes, but a lot of research was conducted first. We should count the time he spent researching what to do as well as the time spent doing it. I'm sure the 12-hour builders did research too, but they probably spent a lot of time on aesthetics, and on optimizing factors that didn't contribute as much to the car's success.
He deserved to be flexing that ex-Nasa engineer title 😅

Would he have done so well against it before slamming into it with his rocket car?
@@josephgarvey2153 I was thinking the same thing! That hit could have easily thrown the other car out of alignment. We also don't know if the Pack is running on the same rules as what he built his car by.

So, KRplus suggested this for me, and I enjoyed it. My grown son did this with his dad back in the day and they were really consumed with creating it and racing it. A bit of nostalgia, and some learning. Thanks!
my husband passed 3 years ago, so now I get to do the dad stuff like this. it's honestly more fun than the normal mom stuff I usually have to do. thank you for the tips!
This would have been useful to me 10 years ago.

More like useful 30 years ago for me, pre-KRplus and internet, so I was screwed either way! Al though my Dad did have an engineering degree, it was chemical engineering, so not so helpful for pinewood derby. We did use graphite back then thou.

30 years ago for me.

Just want to say “Thanks!” Followed the tips and advice in this video with my son to build our first ever derby car. We managed to beat out 101 other cars and take the top spot.
Science works!
11/10 great content! About to shepherd my 5y/o through his first derby. And DANGIT I’m gonna try and let/make him do most of the work, but may have to build one of my own. Would 1000% love to see an updated version of this, too.
My dad would polish the axles super smooth with a sandpaper drill bit. Me and my brother would alternate who won every year. It's hilarious to realize that this was more of a competition for the dads.
It’s just sad for the kids who built their own car and your father was building for you

How many ankles did it break. If you know what I mean.
A crowd of ankles is a better target than a normal crowd, because there are twice as many of them (if we're talking typical humans)

My 8yo ate this video up and did as much as he could with these tips. Dad and I helped very little - just cutting the basic shape and putting on the wheels for him. He set the track record for the year - can't beat that!
My favorite design I (my dad) made, was 2 3d printed airfoils with carbon fiber rod connecting them. Then obviously all the stuff you mentioned here. Honestly it was a pretty cool design. Looking forward to improving it when I hopefully have kids in a few years.

As an Eagle Scout who is trans, it warms my heart to hear of young girls now thriving in Scouting.
(By the way, to anyone who isn't familiar, I'm assuming it's not Girl Scouts because of the use of the word Pack, since Girl Scouts used the term Troop at all levels, whereas Cub Scouts - ages 6-11 - used the term Pack when I was a kid, and that's the age group that did pinewood derby)
one of the best memories I have of my grandfather is how he helped me build my derby car, it ended up being a first place car in every heat but the 'officails' gave me 3rd place because I won too much and it wasn't fair too the other racers (gotta love the "everyones a winner" era of the early 2000s). I was so mad when they gave me the trophy, I threw it across the room.
Best part of racing pinewood derby as a kid was the time spent with my grandpa. He made me do everything except when he melted the lead fishing weights to pour inside. Didn't do anything fancy. Made it to Districts. Still remember working in the shop with Grandpa 35 years later.
grandpa's are all kinds of awesome
Michael Jolley heartwarming man ;)
Didn't have my grandpa around at the time in the late 70s, but a little old man I would visit in a wheelchair up the street helped me cut my block down into something that looked like a car before I started sanding it. Good memories.

Adam Same in Australia, its a very interesting topic on how stuff works and why.
I just love how an American sport has morphed from kids racing blocks of wood to dad's spending hours making precision engineered cars that their kids pretend they made.
Xaiano A dad with integrity wouldn't build the car for his son. But who cares about integrity these days, or, better yet, who cares about teaching their kids integrity?
A dad with integrity wouldn't build the car for his son. But who cares about integrity these days, or, better yet, who cares about teaching their kids integrity?
My dad always gave me a hacksaw and made me do it myself. My first car was fantastic looking and we made it look like a spaceship and it took me forever to build. In the years that followed, I got lazier and ended up eventually just cutting a 45 degree angle in the nose and drawing some flames on it in sharpie. I actually did pretty okay that year.
My father had me draw the shape I needed for the car, and he cut the rough shape. Why? I wasn't allowed to use the saw. It was modeled after the old gremlin my Dad had and got rid of a few years before. I then used my jack knife to carve it how I wanted the rest of it, sanded it. I use model paint to color it. Then in the end I drilled a bunch of holes in the bottom near back, melted some old sinkers in. We used graphite, sure he helped with melting and some of the drilling. but I did a large portion of it. it didn't win, it didn't get last place. Overall a bonding experience.
A dad with integrity would teach the son why his "precision engineered" car wins. And allow his son to do most of the work under his guidance. My dad did that, and because of his teaching i got a hobby, interest in physics, and basic tooling skills which i later refined and now use in my profession (woodwork)
Upforce seemed to help me, in a normal car you want downforce to keep more of the rubber in contact with the road but with Derby you want the less friction possible so sanding an "air pocket" under mine helped a lot, also no paint, just primer and sand smooooooooth for that frictionless glide

If he/she asks why then you are honest "Well, I find your way of explaining quite hard to follow some times"
This is nothing bad, nor says it is bad.
They're people in the learning process and believe me the best feedback comes from the client.
@@hiba756 yay same bud
I love the way he dose that

Same here.. he has a gift
Our Cub Scout pack added some rules to help make it more of a Cub rather than a dad competition. Things like no turned wheels; you could polish the axles but had to do it yourself; age adjusted limits on what dad could do (obviously the little Tigers mostly decorated whereas the Webelos could do a lot more hand work.); and esp build days where power tools and leaders were available so that kids without them (and without dads) could have adult help. We also had an unlimited division for after the kids were done so the dads could show off.
Thank you Mark Rober, Because with your advice, I got first place in my den, and Second place overall, and my brother got first place in his den, and Third place overall!❤😃

Been more than 40 years ago for me. Polishing the axles (nails) smooth, narrowing the contact points on the wheels, adding lead to EXACTLY the allowed weight, Fancy aerodynamic carving and sanding followed by a polished lacquer paint job... Ran in one rally and won every single heat hands down. Of course, as much as I know all that stuff now, I didn't have a large hand in the actual process at the time. I still have the car and the ribbons on a dedicated little shelf in the rec room.

When I was in grade 8 woods class, we did something very similar. Used Co2 canisters to propel our cars across the shop floor while attached to a string. I made a car that was as light as possible, low as possible and the wheels were covered. Fastest car in the class

Fun fact: I met the guy who was the original maker of the kit. The reason the block of wood is the size it is, is because the company also made window frames and they were the scrap left over from cutting window frames.

Maybe a walnut or oak derby car.

@@krisaskew5801 start a local walnut derby league 🤣
Henry Ford used engine crates as beds for the pickup trucks they made. Very smart. I really enjoyed watching these videos. You all have really raised the bar to win or even compete. Thanks!
This really makes me miss my dad.45 years ago he "helped" me build the most beautiful pinewood derby car. He was an engineer, we came in 2nd. The car flipped on the final round. He passed away about a year ago RIP Mike.
rest in peace he does
Sorry for your loss ;(
bro same here only I took first early 70's because of his knowledge & GRAPHITE !!!! we were the only one to use it.....
Also a NASA \ Space \ MIC elec. engineer
he passed in '99
Rest In Peace
@@cameltube-vk7el Lot more recent in the 00s my dad did the same. I forget what kind of weight we used though.
your taking the fun out of it with this video the games are only fun when we arnt trying to win so hard you have gone ahead and min maxed this and thus taking the fun out of it for alot of people
The "ghetto duct tape" is a great tip...we taped the weights down as well...easier to make last minute adjustments than if the weights were glued...thank you for this video, Mark🤜🤛...my son took 1st place today🥇🥇🥇
Watching this 6 years after it was made. I made one of these as a kid and loved seeing this. Had no idea there was so much to it! I was more concerned with my sweet paint job.
Brad Coleman tbh, mine had a TROPHY for “best looking”, in which we all voted on who’s looks the best, so I don’t blame you.
As a kid I got 2nd in state but spent an insane amount of time working on the cars... 60-80 hours+ and really wish I knew some of these tricks back then
I followed his whole video and did exactly everything he said and my sons car was the fastest on the track out of 50 Boy Scouts he won first place thanks to tips and tricks on how he told you to put the wheels and everything
Congrats
👏👏 good job
woooow xD
our races all 4 wheels needed to touch and no wheel mods besides removing injection mold seams
So basically it's a competition between the scouts dad's xD
I just love how KRplus throws these off the wall videos on my feed. They almost never disappoint.
Idk if anyone noticed this, but the transition of the blocks’ color between piles is so smooth.
That's not a pinewood derby car, that's tesla's new cybercar
cybertruck*
@@sorcerer6373 No the cybertruck has different dimensions and has a truck bed in the back. These aren't pine wood derby trucks.
Chris Anderson I haven’t see anything about a cyber car. Only the cyber truck
yeh lol
SAME IDEA
Nobody:
Mark right before the Pinewood derby: PROPANE MAKE CAR GO ZOOOM
Hahahaa veri funy comment
@@danu4763 in fact it is. Sucks to be you to not understand it ?
CO2*
@@befer what?
@@danu4763 this comment is 2 months old I don't even remember
This is gonna help us so much!thank you mark😊!!!!
And just like that, did everything in this video and took 1st place against 42 other cars. Thanks Mark!
When I was a kid my dad basically just gave me a couple of little metal plates and some glue and said have fun
So I made an armored car
You made the Tesla cybertruck
Baby musk
And wheels, never forget the wheels.
I remember my little brother stuck half of a sawblade on top of his car and used design tape that had a flame design, so the flames didn't have to be painted on...he won for Best Design, and I'm still not really over it. I mean, how did he qualify with that sawblade?
awesome
Randy Marsh accidentally discovered warp speed during a Pinewood Derby build for his son back in 2009. True Story.
^^
Haha gd on randy he is a true genius. I remember he dressed up as princess leia too steal the magnet
That's the same year Princess Lea was caught breaking into some lab if I remember correctly.
Shhhhhhhhhhhh or we have to give back the money
Lfmao
I loved Pinewood Derby back in Cub Scouts! I got 3rd place with my2 half oval shape, painted silver.
Not sure when this changed but there are clear rules and guidelines now about polishing , wheels touching, width , length (weight 5oz which has always been), bottom clearance , width between wheels etc.
We did this and it TOTALLY worked! First place! Thanks a million. That's after getting last place last year and second to last the year before.

Excellent video on the basic physics concepts needed to have a successful pinewood derby car. My son has raced in our RA (Royal Ambassador) race at our church for 4 years and I have helped him work on his car (and yes he does a vast majority of the work [with my supervision and teaching about concepts in physics]) using most of the concepts in this video.
Our church buys kits so we have a precut shape already made for us when we get the kit. But my son sands his car, finds the balance point (Center of Mass), drills the axle holes, sands and polishes his nails, polishes the wheel bore, drills the holes to add weights, paints his car, and puts on the graphite. I help hold or act as his "assistant" when he needs another hand. I help put putty in the holes when we add weights (because it is messy and my son gets a skin rash from the wood putty) and I help push the axles into the holes while he holds the gap measurer (he is not strong enough to insert them by himself). So I would estimate he does 80+% of the work himself, but with assistance and supervision from me for proper technique and safety purposes. Each year as he gets older, more experienced, and physically coordinated he needs less and less of my help.
I already understood most of the concepts needed to build a fast car through my education, but researched ideas/concepts as we prepared each year. We aren't allowed to run on 3 wheels, so we have never attempted that technique. He has won every year and our goal has become to run faster each year by trying a new technique or perfecting one we already are using. The only thing we haven't tried is rail-riding and we plan on adding this technique to his car this year.
Here is what aggravates me about all the whiners and complainers: They almost all insist that (because he consistently wins) my son has no input into building the car. These are the same dads and mom who spend no time with their kids, slap a car together the night before the race with no thought about the car (because they have their lazy butts on the couch watching TV for hours on end), and could care less about spending quality time together with their kids. My son and I talk a good bit about the construction of his car, but the truth is we spend more time talking about life (God, the value of reaping the reward of hard work, his fears, aspirations, friends at school, his favorite class, movies, baseball, and even girls). The time we spend together during the building of his car is fantastic father-son time. The bonding and fellowship is why dads should invest time, thought, and effort into helping their kids build a car (winning is an added benefit and a by-product of a dad "being there" for his kid). The sad thing is every year I offer to have several weekend workshops where all the dads/sons can get together and we (me and my son) will help them with their cars. Sadly, not one has ever shown up for help. I have even had a few of my sons friends over to help them in bits and pieces work on their cars and yet not seen a single dad show up. How sad is that? These are the same dads (and some moms) that make accusations of the car being totally built by me or worse yet, that we are somehow cheating to win.
So again thank you for this great video. Dads and moms; spend time with your child building his/her car. Use the ideas and techniques in this video to make it fast. You may not win, but at least it will be competitive. You and your child will learn something about science, math, and physics. And miracle of all miracles, you might learn something about your child that you didn't know before by spending extra time with him or her.
+Lee Borcik Wow
I love how easy he makes things to understand for incompetent people like me
The colored blocks especially were a nice touch.
😂 your such a nice person
Who ever has the most green blocks wins!! now let’s count them, can you count with me? Let’s see uno dos tres🤣🤣
i understand it, but don't have all the tools he used. I'm a female trying to build this car with no tools for my son. My son's going to be devastated.
@@BrendaMLKovacs aight
Thanks so much!! This helped me through my first Pinewood Durby!!:)
Cool engineering, love the explanation. Science does work!
