Origami Waterbomb with Participation Prizes

This is a really fun and simple traditional model. You make a box in which you plow air like a balloon.

Diagonals and halves(helps to do one of the halves in the on the other side)

Waterbomb base

Fold the corners up

Top corners to the sides

Toward the middle now

Moving the middle corner out of the way(up) fold the left and right corners to the middle

Now you have to insert the little triangles inside(left side half in, right fully) you might have to open it up slightly for it to fit

Repeat everything on the other side

hold the model like this, spreading the gap a bit and blow(don't hold to tightly)

Here's a nice detailed video if you're stuck on any step

And finished :D

On another note, working hard on the new papercraft, Paranthropus boisei knmer 406, I got the 3d image of the skull here and designed the model using pepakura and blender. I didn't want to remove too many features but kind of regret it now, I don't think I'm halfway done.

Anyone who makes the waterbomb gets 0.1sbd, hf and gl :D
