How to Make a Paper Water Bomb

First,if you have only letter paper like me,you'll want to cut it to a square. Then you should fold it diagonally both ways and unfold both ways.

It is quite hard to explain so I'll let the pictures do the talking.

First you will want to fold the first two points upwards. Second you will want to fold the two little points inward. Third you shall want to fold the upermost points inside the little pocket-like folds.

Fold both side's points forwards and backwards.

Blow into the end that has a hole,fill with water,and have some fun!
