The waterbomb base consists of:
»Two perpendicular mountain-fold and
»Two diagonal valley-fold that intersect at the center.
The paper is collapsed along the creases to form an isosceles right triangle with 4 flaps.
It gets its name from the famous origami waterbomb model.
It’s interesting, if the folds in the origami waterbomb base are reversed. Then an origami square or preliminary base is formed.
