1. is it possible to drive a car across a lake's surface? i would imagine a four wheel drive vehicle with the front wheels spinnng faster than the rear wheels would do the job, at a high speed, especially if the tires were slick

think this could work? and if so, any idea what speed/weight ratio would do it?

2.

3. Try it, You'll need a really deep lake though, so that the water is very still. A shallow lake will have many snall waves which will very easily break the surface tension.

4. Yeah try it and die

yes, its done all the time in iceland with those custom hillclimber 4x4 also snowmobiles

cant remember the name of the effect it uses, same as skimming stones on water

they raced them on uk tv, one against the other over deep lake, just needs a run up to get speed, then dont let go of throttle

so yes its done all the time :-D

Absolutely! It has been done many times, but you have to be careful. You wouldn't want the ice to break! :wink:

(Isn't it funny how we assume to understand an unprecise ambiguous question? Nothing in that question suggests liquid water.)

7. theres an equation for this, but i cant remember the name of it begins with B, it was firstly to do with skimming stones over water, but still applies. Its the reason bare footed water ski'ers stay up

Someone must remember the name of it

8. heres a video of car over water

knew id get it in the end :-D

10. I presume no. Either you need to have to wide wheels to make the pressure to reduce.

check the youtube link a couple of posts up. it shows it in action :-D the sound drops out of sink a bit but still worth watching :-D

someone called LydĂ©ric Bocquet came up with a calculation after watching people skimming stones over water

12. I need to go to iceland now, i wanna see this for real
