Water Bomb (Eric Gjerde)

Update: I was made aware of the fact that Ron Resch discovered this origami tessellation before Eric Gjerde. I have updated the list of designers accordingly.

This model somewhat reminds me of a hedgehog. It's basically a tessellation consisting of many small waterbomb bases.

Paper: 19.5cm square of stiff paper, 115gsm
Model: 11cm x 11cm x 1cm when pressed flat


are there diagrams that are not in the book

i would really like this if i could print a cp without buying this book

I know this is probably going

I know this is probably going to sound dumb,but do you know if there is such a thing called a waterbomb?Also,why is the base called a watebomb in the first place?I'm just curious is all.

Waterbomb base, waterbomb model

There's a waterbomb model, which you can actually fill with water and throw. The waterbomb base is how you start the waterbomb model. As with most bases, they're named after a well-known model that starts with that base. Hope this clarifies it.
Check http://dev.origami.com/images_pdf/trad_page2.pdf for diagrams for the full waterbomb model.

would my creation be counted as a "tessellation"

by what i understand a tessellation
is an origami that can be repeated
know my origami doesnt look like a tessellation, but neither does the apple (that is why i asked)
well i am my able to make origami from a 32 and 64 (and hopefully a 16...)
would that count my origami as a tessellation?

Tessellation or not

This is totally taken out of context. Which model are you speaking of? :)
In any case, the apple by Shuzo Fujimoto isn't really a tessellation, but it's a tessellation-style apple. As to the exat definition of tessellations - you may also say that the clover folding and the hydrangea aren't tessellations. But does it *really* matter what the exact definition is? I'd say just enjoy folding, and don't worry too much about how to define the different areas of origami - there will always be an overlap and gray areas. :)

Would you...

Would you make a video about how to make more waterbombs because i could see that there is more squares on this one than the one on the video you made.

No big difference

It's the same technique, just start with a grid that has more divisions.

hi Sara will you please make a video on this model?

Does it have the same

Does it have the same principles as the the traditional water bombs do?

(such as holding water for a sufficient time, in which allows it to be thrown against some one)

It's not a closed shape, so

It's not a closed shape, so .... no.

that's really cool! it's

that's really cool! it's great how it's more 3d than just tesselaty.


yeah you're right! it does look like a hedgehog. by the way, the crease pattern can be found on the origami forum by Mark Leonard:
