Description: This trick creates a loud popping sound when performed right.
Find a straw. The thick, malleable ones from McDonald’s work great.
Pinch each side of the straw to seal off the air inside.
Begin winding up the straw so the air inside increases pressure. Wind it up to about two inches.
Get a friend to flick the pressurized middle.
The straw will crack.
Result: Pop! The straw explodes and emits a loud pop!
