How do you make a paper water bomb?

A paper water bomb is also called a water balloon. It is made using simple origami and can be completed in a few minutes.

The starting point is a perfectly square piece of paper. Then, follow these steps.

1. Fold the paper diagonally then unfold it and fold the other diagonal. Unfold to leave a square piece of paper with an X.
2. Turn the paper over and fold it in half, top to bottom. Unfold and then fold in half left to right. Unfold again.
3. Collapse the paper using the folds to create a triangle.
4. Fold the left-front corner up to the top of the triangle. Do the same for the right-front then flip over and repeat so that all four corners are folded up.
5. There are now four horizontal corners €” fold these to the center to create little pockets.
6. Fold the flaps above the pockets so that they can be pushed in. Turn over and do the same on the other side. The flaps should now be inside the pockets.
7. Unfold the water bomb, and a hole will appear at the bottom.
8. Gently blow into this hole to expand the paper and create the balloon.
9. Carefully fill it up with water using the same hole that was used to blow it up.
