Ok so the light props the props that everyone uses and is used to are switched with the weight of the heavy props so something like the barrel would sink as much as the locker usually and the locker would float as much as the barrel or something like that you know add a little twist to the game.
Someone thought of that by the way, make sure u look at all the other ideas by others before you make yours
Its okay to reinforce an idea, but this event may lead to slight disaster. Locker + Car = cancer to me ;p, but i'm curious as how this will turn out
I suggested this idea a while back and it was shot down due to the time it would take to flip all of the weights for all of the props.
