Don't worry! Mark Rober is cool with us sharing his awesome video.

My daughter took first place this weekend, we used this video for help and boy did it work. We never lost a race all day!!!!

My son placed won first place in the Pinewood Derby at our local church. Thanks for making a video my eight year old can understand. Great job!

Great teaching principles. Good work with the blocks. I showed this to my kid 6 months ago and he didn't care about any of this. I showed it to him after he built his car and he understood why he was going to lose big on speed and will have to win on character instead. Next year hopefully he will use science to make a more competitive design and car..

this year was our first on the derby , I build the car following all your tips and we got the 2nd place, my little Tiger was super happy, thank you for sharing!!

What shape did you cut the block? And did you use the bending machine?

Helpful video. Had our race Saturday. First car my son and I have ever made. We came in first in addition we won all our races and came out undefeated. We are on our way to some District race in next month. Thanks for all the help. On a side note one of the parents was really salty.

Thanks for making a trimmed down version of Mark's video. The original was already the most kid friendly derby science video on youtube but the edits for this have made it even better for short attention spans.

Just want to give u serious props! 1st year they did Pinewood Derby in Girl Scouts, my daughters took home 1st and 2nd Place! They really liked your video and the info used worked so well!

Thanks for making this video!! My son is a huge Mythbusters fan and we wanted to find a video that scientifically defined what was important in designing his car. We took a pre-cut block and focused on just the weight distribution and the polishing of the axles. In his first year he took second based on the information in this video! (we only had a few hours to build it, paint etc.) Thanks again!

This is an excellent video! Not only explaining what to do but why it works.

also learn how to polish the bore hole of the wheel and use Pledge furniture polish on your axles after polishing them. use compressed air to blow out any dust in the wheel bores. do not add graphite to outside of wheel. use in bore hole only.

That guy is Mark Rober!

taking notes on this was my hw

Same thing here first time we ever built the car went by your steps won first place

We check for all these especially the bent axles and the 3 wheel. but like he said you don't need to spend money and time when just a few thing will help more. the machined axels are a waste of money.

What is the tool used to bend the nail?

It did so good that my car sped past the speed of sound causing a mini sonic boom that obliterated the other cars and i was disqualified... Worth it

I won my pinewood derby

My son won first place again by using these techniques (three years back to back)

pretty cool

Fyi I used this principles and today my son won first place at irondeqouit ny's pack 420 pine wood derby. And not only did we win but we killed it. out of ten runs down the track we came in 1st on all but 2 races which we came in 2nd. Those races we were in the second lane which was the slowest lane by far. Not a single car won a single race in that lane. When we win in the regional s I will update this comment

Did you win regionals? I never won council, but i won district twice

Well i wish someone would have told me this back in the day i finished getting my eagle rank before even thinking about this as a kid lol 2006 was yesterday right ? Lol

These videos so many memories of building my car with my dad and finally beating the engineers kid never seen my dad happier.

Mark let them use this

Lol school homework

I love you 😘😍❤️💩

Is this technically copying mark rober?

First year doing scouts and we had no clue how to do the derby car. Followed your video and our little tiger took first place in the whole pack!!!

Ditto....

We watched your video. Followed your suggestions. And won every race.

Thanks for the video followed it when helping my son with his car I've never built one before we won every race last year until the car flipped off the track in the finals and bent the axle took the same car back this year and won every race won our division then won over all fastest out of all division thanks again.

First Pinewood derby entry ever, and we were the fastest in our whole troop by following all your advice! Great video and information, I knew I had come to the right place as you broke it down scientifically!

Just finished our first pinewood derby with first place overall in the pack. This video was perfect! Thanks!

My son followed your advice and got 1st in his den! Thank you!

Hey!!!!!!! No kidding. We have NEVER participated in nor watched a Pinewood Derby. We followed your video, multiple times, and won every race - and we entered 2 separate cars. We used the same instructions for both cars and each car won 1st place! We also won the grand prize trophy for fastest time. Phew!!!! Awesome video!!! Viewers: 1) pay attention to where to place the weights, 2) get as close to 5oz as possible - seriously...we weighed in at 4.98oz & 4.91oz (we ran out of weights or else this would have been at 4.97oz, 3) ride on 3 wheels, 4) bend the wheels as instructed , and 5) do NOT forget the graphite. #5 is critical as we witnessed a car unable to make it to the finish line. We witnessed that same family add graphite to the car after the race and the car crossed the finish line. This was sooo much fun as every member in the household had a hand (literally) in building these cars. My family and I WILL be racing our own respective cars next year - awesome experience. Blessings race fans!!!

Great video! This amateur dad/son appreciate the tips. Watched many videos & some are crazy detailed & time consuming. So from another video I saw extending the axel length helps. What do you think about that and/or sticky nose?

You say that the axle/wheel contact area is not critical to friction but the closer the interface between axle and the wheel is to the center, the lower the velocity between the surfaces is. Some graphs of friction show it to be linear with velocity depending on if it is wet or dry friction. Graphite seems that it might be a kind of wet friction because of the very small particles at the interface.

lolol same here, did all the tips allowed, i.e. weight placement, rail riding, graphite, profile ... and my Tiger scout won the pack! He even beat out the adult bonus group. His average was way ahead of the next placed car.

Very helpful

Just thought I'd let anyone who's watching this know that that guy is Mark Rober!

#6 is key if u can roll the car on tile floor and it goes straight for forty feet ot will be competitive regardless of all the others not being perfect, adjust axles to run straight

a properly aligned rail-runner will always beat a straight-runner... all else equal

We do not have pinewood derbies here in Australia ,But being a pensioner I am very interested in making cars as a hobby and maybe building my own home track , But i have a couple of questions that i have not seen any info on , weights are they more effective down low in the car on the track or higher up off the track in the car body , and is it better to make the car light as possible so you can add more weight at the rear of car .

What did you use for weight on top of the car?

thank you for this it was very help full =()

we are building ours for a boy scout meading

The rotation kinetic energy said 8o but Reverse

Delit dis video, my ticher is telling me to see this

hola

Do you bend all four axles 2.5 degrees???

@oxxxeee

5 жыл бұрын

just back axles are critical. bend front axle so you can align the steering of touching wheel

We were disqualified last year 2 days after the race.

My car won the whole pack. Use these tricks

cool

are you mark rober

We followed the 3 wheel but then our pack told us no 3 wheel :(

!

This is not you're video

Riding on 3 wheels is illegal .. It’s in the rules now. Don’t do it we had to change nails no time to tune and lost!

lolololololololol .-.
