The Wooden Bridge

[Ben_10_000]

Your car will be sent into a very weak wooden bridge beneath a really strong gushing river. When the bridge finally gives in, the car will be sent down, leaving it to float away, and proceeds to fall through a waterfall, and will be crushed by the impact of the rocks set down there.
