You’ve heard about gears, transmissions and dog boxes, but do you know why your car has Helical Gears and Race Cars have straight cut gears? What's the difference between helical and straight cut? You’re about to find out! It’s Science Garage!

Bart teaches us how cars work by blowing stuff up and cutting things in half. It’s a science show for the car lover who’s easily bored. Join Bart as he explains the science behind everything automotive. This is cars down to the atom. This is Science Garage.

Some of our best videos ever are coming out soon, stay tuned so you won't miss a thing!

You know, normal cars(with a manual transmission) do have some straight gears: the reverse gear. Ever heard that weird noise when you're reversing? Thats the straight cut gears.

[Alexwaltman]

I miss this guy and this type of script writing. I forgot how much better Donut use to be.

[andrewg]

Straight cut gears are awesome, used them for years.

You can't argue with me because my tinnitus screams louder than you can <3

[TheMelodySweet]

Bart failed to mention just how badass straight cut gears sound at speed. As a mechanical engineering student I love watching your videos, they are educational as well as entertaining, I think you found the right balance of being educational without getting too bogged down and bored by the theory and math behind the concepts

[Mikey]

Bring back this series. It's the best car explanation series on YouTube.

[JuanPerez-yghj]

Why is it called science garage if the whole thing happens in a kitchen?

[puderrick]

How familiar with the gear wars are you exactly?

[aarontena]

"The second thing I like to grind is gears"
But what's the first one?
*Concern*

[Fidelitye]

Am I the only one that knows what straight cut gears are because of The BMW M3 GTR in NFS MW.

[ArbaazKhan-egqc]

Take a shot everytime he says 'gears'

[schmid.]

Missed the most obvious pun, Richard Gear.

[bassam_salim]

The reverse gear is a straight cut gear in all cars and that's why reverse sounds louder, right?!

[alexbbruce]

Damn, I miss having this dude on Donut

[Subtlepasta]

As a mechanical engineer, we needed this kind of enthusiasm in undergrad!

[brianpayne]

Bring back science garage please, these were (still are) great!

[Crypticdragon]

I hope Bart is doing well. I miss watching him explain stuff like this.

[ewatfred]

"Cars that like to go fast" is up there with "The bus that wouldn't slow down"

[zeelax]

Man, this guy is so awesome! Anyone knows what is he doing these days? I'd watch more of his videos. Same goes for the script writer

[gremlincc]

Jessica started a land war on an Asian Continent

[marekkielar]

I love the whine of straight cut gerars! Its the best accompaniament to motor sound, even better than turbos and superchargers IMO.
