How to Make someone faint

This is NOT fake. To make someone faint, first have them squat down and breathe in deeply for about 10 seconds. Then, have them stand up straight against a wall and hold their breath. Get someone else to push hard against their chest. The person standing should then lose concsiousness for a few seconds! WARNING : This is dangerous and I am not responsible for any injuries/deaths that may occur. I do NOT encourage you to try this. Use this as inspiration for one of your April Fools Day pranks!
