Place it at the exact beat a phone leaves a hand in the edit, then follow it with a shocked sound for the frozen reaction and finish with the Oh No No No Laugh once everyone realises the phone is fine.
Über diesen Sound
This just under eight second effect recreates a phone hitting the floor and its screen cracking apart, with sharp splinters followed by smaller crunching and tinkling glass sounds. It feels sudden and painfully convincing, sparking a split second of panic before relief sets in. That jolt is the whole joke, turning a staged drop into a brief scare that ends in laughter.
