There are two ways to make a good paper popper that I am aware of. This Instructable will show you how to make both. Out of a piece of paper you can make a big pop that scares the people around you. This is great in school if your teachers don't care or you don't care to get in trouble.
Step 1: Materials
To make both of them you need to get paper, The lighter the paper the louder the pop, but sooner the rip. I suggest using notebook paper, it works great.
