Water Bomb Base

This is my first time working on origami after I got a book on origami from the library that I decided to try out. Not too shabby for a first timer if I do say so myself. ^.^ Should've used colored paper though, but wanted to try on normal white paper as a starter. ^.^ This origami is called the Water Bomb Base. Not sure why they call it that. Never seen a water bomb look like that. Still cool.
