How To Make An Origami Water Bomb (Paper Balloon) - Video
To make a waterbomb, the first thing you need to do is to create the waterbomb base (hence the name of the base) If you are struggling to do this, then click on the link to waterbomb base above: If you scroll down a bit then you can find a video and instructions. To make the waterbomb base, you must fold both diagonals and then flip over and fold one horizontal. Pinch the edges that the horizontal line joins up together and then squish to make a triangular shape this should then be creased. Then you need to fold the bottom left and bottom right corners up to the tip at the top to create a square shape. Repeat this on the other side. Remember to only fold up the top flap on each side. Then hold the square so that it makes a diamond shape and fold the top flap's left and right corners into the center. Repeat this on the other side. There should be a flappy triangle at the top of the shape now, fold this along the edge of the triangle at the side and then tuck it into the pocket that is in this triangle. Repeat on the other edge and then repeat on both edges on the other side. Now, take the top flap from the left and fold it over to the right, turn the shape over and repeat. Hold the edges securely and then blow into the hole at the top to inflate the waterbomb.
Now you have your finished waterbomb and can create all sorts of mischief with it. You can now fill it up with water and throw it. Or you could deflate it put it in your pocket and blow it up at any time that you want.
