How to Make a Water Bomb

Take a square piece of paper (don't use origami paper, it would be a waste. Use printer paper, fold it diagonally at the top and cut the strip.You can also use waxed paper to better contain the water.Or you can use oil with the paper to make it water resistant.It works in every way!).

Fold the paper in half diagonally and unfold it again. Repeat in the other direction.You will get an X on the paper.

Turn the paper over and fold the top and bottom in half.

Turn the paper over again and press in the center, while folding it inwards along the creases. You will get a triangle.For a more detailed explanation you can read the specific article on how to make an origami triangular base on wikiHow.

Fold the folds on the front towards the center. Repeat with the ones in the back.You will get a square.

Fold the side corners towards the center line. You should get a small pocket.

Push the folds above the pocket inward.

Repeat these last two steps with the other side.

Blow into the hole at the bottom to inflate the water bomb. If you use waxed paper this step may be difficult, so use a straw to blow.

Fill the water bomb in the sink.
