Origami Water Bomb





Introduction: Origami Water Bomb

Need a water balloon but got no balloon? Regular old paper and skills of a fold-ist will have you drenching your foes in no time, with stile to boot.

Step 1: Parts Layout

(1) a sheet of paper
(2) a second resource for showing how to do this origami: http://www.fishgoth.com/origami/basics5.html

Step 2: Square Your Rectangle

tear (or cut) paper to make it a square. Fold the paper as shown in the picture and tear the flap. A clean tear can be made but folding along the tear line multiple times and licking along the crease (avoid paper cuts!) then tearing.

hopefully the pictures on this slide show what's going on.

Step 3: Fold and Label Square

Make creases from corner to corner and mid-point to mid-point across the square. A good crease forms when folding the same line forwards and backwards a few times.

Then, label the ends of each line as shown in the picture. (these labels can be "mental labels," for book keeping)

Step 4: Begin to Fold...

...but don't give up! (get it?)

fold points 1 and 2 onto 3 and A to A' and B to B'. Do it in one fluid motion and it will look like the picture.

Step 5: Fold Up Corners of Base

now that you have this folded-alot-triangle (from last step), fold the two free edges on each side to the top corner. Turn over the base and do it to the other side, too.

Step 6: Final Folds

fold in corners, etc. etc.

Step 7: Blow Up, Fill With Water

Questions & Answers


did you get it from "easy origami" by john montroll

nice but to easy

there is a you tube video on how to make these except you fill it with gas from a lighter and put the flame at the small hole. They call it a paper jet engine

when i did it, my friend is watching. I sill it w/gas, light it, and POP... "OUCH!" It shot forward, curved, and hit my friend in the corner of the eye

would the water drench the paper? making it kinda usless?

not if used immediately. and you could also try making it out of wax paper.
