Instructions to Build Water Bombs

  • Take the top-right corner of the page in your hand and fold it diagonally down and align it on the left edge of the page.
  • The crease should go from the top-left corner to the right edge of the page.
  • Open the page out again
  • Take the top-left corner of the page and fold it diagonally down and align it on the right edge of the page.
  • This make a diagonal crease going the opposite way to the one in the first step.
  • Leave the page folded.
  • You have a triangular shaped flap that was folded over in the previous step.
  • Cut off the section of teh page that is below the triangular flap so that all that the remainder of the page is square.
  • Take the bottom-right corner of the triangular flap and fold it over onto the bottom-left corner of the triagular flap.
  • Crease the paper vertically from the point where the two creases from the first two steps intersect.
  • The page will be three-dimensional now. After the next step it will lie flat again.
  • Take what was originally the top-right corner of the page and fold it down to where the right edge of the page comes diagonally inwards.
  • Make a vertical crease in this new flap similar to the crease you made in the last step. This new crease must be next to the previous crease
  • Take the bottom-left corner of the triangular section at the top of the page. Fold it up to the apex of the triangle.
  • Take the bottom-right corner of teh triangular section and fold it up to the apex, too.
  • The triangular section should now be diamond shaped.
  • Turn the page over.
  • Repeat the previous step on this side of the page.
  • Take the left corner of the diamond and fold it to the centre of the diamond. The crease that you make should be vertical.
  • Do the same for the right corner of the diamond and then again for the reverse side of the page.
  • At the top of the waterbomb (or perhaps the bottom if you have turned it upside down) are two loose corners. Take one of the corners and fold it down over the top edge of the flap that you folded in the last step.
  • Do the same for the other side and the reverse side of the page.
  • Take one of the flaps that you folded in the last step and fold it in half.
  • Do the same for the other side and the reverse side of the page.
  • Take one of the folded-in-half flaps and lift it up.
  • Underneath it is another triangular flap which is actually a pouch. Open the pouch up and push the folded-in-half flap into it.
  • Do the same for the other three flaps.
  • At one end of the water bomb is a small hole.
  • Find the end with the hole and, with a pair of scissors, snip off an extra 2 mm of paper to widen the hole.
  • Open out the four sides of the water bomb.
  • Blow into the hole so that the water bomb inflates.
The water bomb is complete! All you have to do is fill it up with water and peg it at someone before it disintegrates in your hand.
