You don't need a latex balloon to make a water bomb -- just paper and this quick lesson in origami, the Japanese art of paper folding.
Step 1: Take a square paper Take a square piece of paper, fold it over diagonally, and crease the edge, so you have a triangle. Open the paper flat again and cross over the other side diagonally, creasing the edge, so that when you spread the paper square you now have an "X" in the middle. Now fold the paper in half, from top to bottom, and crease the edge.
Step 2: Fold the sides Take the top right corner and tuck inward, toward the center of the paper's bottom edge, and press. Do the same with the other side. You should now have a triangle.
Step 3: Fold again Take the bottom right-hand corner of the top layer of paper and fold it up so that it meets the tip of the triangle; crease the bottom edge. Repeat with the other side. Now flip the paper and repeat on the reverse side. You're halfway through to making your paper balloon water bomb!
Step 4: And fold some more Holding the paper like a diamond, fold the right tip of the top layer over to the crease in the middle of the diamond. Repeat with the left side. Then flip the diamond and repeat with the reverse side.
Step 5: Tuck the wings Take the 2 wing flaps and tuck them into the pockets that have been formed. Press firmly and repeat on the other side.
Step 6: Find the hole and blow Find the hole at the bottom, hold the paper loosely in your hands, and blow to inflate the paper balloon. Fill it with water and you've made a paper balloon water bomb. Now just be careful who or what you toss that water bomb at!
FACT: Englishman Edgar Ellington accidentally invented the water balloon in 1950 while trying to create a waterproof sock.
