How to Make a Paper Cracker

Take a rectangular piece of paper.

From the length side, make folds 3 times.

Fold the paper in half leaving the folds outside as shown above.

This step is a bit tricky. So follow the images above.

Now hold it from the bottom, blow into the two heart shaped big holes, take it to the top and smash it down as hard as you can, just make sure it doesn't go out of your hands, do not crack it near your ear; it has a very loud pop.
