Car powered by can of tomato soup.

Main Question or Discussion Point

Hey I am working on a project where I have to make a car travel EXACTLY two meters, no more and no less, and it has to be powered somehow by a can of tomato soup. You can
use the soup inside the can or just the can alone. Does anyone have any ideas or information that can help me? Thanks!

I'd use a hamster trained to eat tomato soup running on a treadmill.

Sorry, it's an absurd question, but very amusing.

The problem is that 'powered somehow by a can of soup' doesn't give enough information.

Welcome to the forum, sorry I can't be of more help and thanks for a good laugh.

Just on top of my head. I am not an engineer yet. How about using gear ratios to take advantage of the weight of can of soup. Maybe using 2 meters of rope to move car 2 meters? Just a thought.


Added:

Now that I think about it, would need alot longer rope due to ratio of gears.

what about turning the tomato soup upside down, open a tiny hole so it pours out, then use a watermill type structure to move the wheels with the force given by the pouring soup...if that makes any sense.

That makes perfect sense. I think it is a better idea than what I had.

You could put the car on a 2m high table, tie the car to the can with some string, drop the can off the edge of the table, and create enough friction on the car's axles to stop it when the can touches the floor.

LOL. When I first read this, I thought it was a joke because I pictured a full-size car. But the OP must mean a toy car. Sheesh.

:uhh: I was thinking of full-size car also. Oh well. If it was me, I might still use full-size car for added challenge. :biggrin:

Strangely enough, the very first post that I ever made on PF was similar to this one. My advice is the same now: if the rules don't prohibit it, just either build a wall at the 2-metre mark or tie a 2-metre string to the car that will stop it dead at that distance.

Maybe you could mount a pump-action water gun to shoot tomato soup out the back of the car like a rocket.

I knew someone who did that on a frightening level. The diagnosis was 'irritable bowl syndrome'.
