Hot Wheels for adults!

[Tunnelcat]

Bet you thought this kid's toy could never be done in full scale, did ya?

The second car didn't fully clear the edge of that final jump though. Bounced really nice.

:O

They almost didn't look like they were going fast enough to make it all the way around the loop.

Never mind Hot Wheels, they must build something comparable to fullspeed Trackmania maps to impress this strange creature who isn't sure whether he should be a fox, a panther or a griffin...
And they must do it on city roads in Tokyo. And then hold an actual race while spectating snipers pick off all the drivers.

So... What to do with the ramps? Now that they've done it...

[TigerRaptor]

Recycle them I guess.

Fun!

Amusement Park rides for Hot Wheels addicts?

Next they'll have to do double loops I guess.

Cool!

They almost didn't look like they were going fast enough to make it all the way around the loop.

Two reasons for this:

1. There's a difference in scale, but no difference in gravitational acceleration. [To visualize the difference, imagine the car falling from the top of the loop - it would take considerably longer than it takes a toy car to fall from the top of a toy loop.]

2. Little toy Hot Wheels cars need to be given enough momentum to carry them through the loop. Those cars didn't need as much momentum, because they provide some of their own force while driving through the loop. [This one is analagous to the reason why rockets don't have to reach escape velocity to get into space.]

Cool!

Hot Wheels never die.

It still "appeared" slow when they reached the top of the loop, even though they experienced around 7g's inside the loop.
