from tokyo, has this system that powers the car when you drag it backwards (dunno the name in english, but basically like hotwheels), and is fast as hell!
I posted pics of it before, but...

too bad this $10 watch only lasted 2 weeks...

 

Man eats car; film at eleven.

 

le car,

Haha...great picture. That watch is crazy...

 

Does putting it in your mouth increase performance.

 

Hey I used to have alot of these little cars wen I was younger.....these are small little spring loaded cars that you put a penny in the back clip and they do wheelies until the spring "unwinds"...I think they were called PennyRacers (by Mattel).

 

I think when I was younger, I'd put my toys in my mouth too.
