Okay...I'll see what I can find...also the links still work..just have to right click them and save to play.

 

no matter how foolproof something is- there will always be a better idiot......

with regard to the tunnel thing.....i think i have seen it too-im positive i remember it from somewhere..
anyway, if a plane can create lift from a wing, and take off; surely a wing can also make you stay down.......common sense prevails!!!!!!!!!!!!!!!!!!!!!!!!!!!!

 

It's simple...If the force created by air (which can be great from what nature shows Florida) is greater than the weight that gravity places on the car than...it can fly technically. Therefore it can drive upside down. This has been a Miseducation by 6thgen. Aeordynamics do no more than force air in the appropriate direction for the desired results. Up, down, out the way, etc. For cars made to drive a up to 200+ mph...The force is obviously down. Because when lift is created...you get to see the videos above.

 

all the vids worked for me, that was crazy. but cool

 

well since (bear with me, my physics is a little rusty)
weight = mass * gravitational force

if the downforce is greater than the weight it would create lift while upside down-thus making the car 'stick' to the roof of the tunnel- since gravity is a constant the lighter the car, the less downforce needed

not sure if this is entirely correct; but i think you (remington) could prove that your right by a formula????
