Here's a fun and ridiculously easy paper toy for Summer. (Or Winter if you're crazy like me.) All you need to make this is a sheet of paper. I reccommend using construction paper, as it's more durable than note paper and will hold water longer.
Step 1: The Paper
Start with a plain sheet of paper. Fold it into a perfect square, and tear along the fold. Now you're ready to begin.
Step 2: Folding
Fold two diagonal lines and one horizontal line.
Step 3: Folding
Bring sides A and B together to form a triangle.
Step 4: Folding
Fold up the two corners of the triangle.
Step 5: Folding
Fold the two triangle's corners in towards the center line.
Step 6: Folding
Fold the two triangles down into the pockets you've made. THis can be a little tricky, and you might want to secure them with tape if it's your first time doing this.
Step 7: Repeat Steps 2-6
The paper should then look like this.
Step 8: Last Folds
Fold and unfold along the lines shown. This helps the bomb inflate easier.
Step 9: Finished!
Blow into the hole at the top of the paper, and your bomb should inflate like a balloon. Now all you need to do is fill it with water, and find a high place to drop it from. Have fun, and don't soak anyone without permission! This is my first paper folding instructable. If you like it, let me know and I'll make more.
