Instructions on making cheap, easy water balloons just out of a square of paper. If you don't have pre-cut squares, you can make them out of rectangular sheets by cutting them into squares.

Step 1: Folding

First fold your square in half diagonally. unfold and repeat on the other half.

Step 2: Folding

Now turn the paper over and fold in half whichever way you want. (unfold)

Step 3: Folding

push down in the center of the square and the paper should fold inward. Collapse so the paper forms a triangle

Step 4: Folding

Fold the two bottom corners of the triangle to the top. Repeat on the front and back.

Step 5: Folding

Now the paper should look like a diamond shape. fold the two outer corners in. Repeat on the front and back.

Step 6: Folding

Now the most complicated part, at the bottom of the balloon their are two corners that stick out. Fold these into the two triangle flaps. Repeat on the front and back.

Step 7: Inflating

Now to help form corners when inflating, fold the bottom and top corner to the middle and unfold. After you've done that, open up all four sides. At one end of the balloon there is a hole. Blow into it and it should puff out into a balloon.
