What happens when someone throws a phone onto a mattress?
The phone hits the mattress and causes a momentary indent on the mattress. Depending on which part of the phone hits the mattress and the angle as well as speed of the throw, the phone may jump to another spot on the mattress, or it may stay where it first made contact. Regardless, it will likely bounce a few times and then eventually stop moving.
