Algodoo

Two crooks steal a solid gold nugget from an antique shop and are on their way to cash in their treasure when they accidentally take a wrong turn. They end up on an icy wasteland. It is so cold that the motor of their car freezes and they have no way of getting back to the main road. Luckily, the crooks are trained physicists and devise a contraption that is able to get the car in motion using only the gold nugget.
