How to Fold the Origami Waterbomb Base

Updated on 02/10/24

The waterbomb base is a traditional origami design that can be used as a starting point for many other origami creations—such as the traditional origami fish!

This easy base consists of only five steps and takes about 1 to 2 minutes to fold.

To fold this base, you will need a single square sheet of paper— origami paper works the best and will provide you with cleaner creases.

If you use a multi-color sheet, you will want to begin the fold with the white side facing up and the colored side facing down.

Step 1: Fold the paper in half vertically and crease

Start by folding the paper in half horizontally—bringing the top edge of the paper down to the bottom edge. Crease well.

Step 2: Unfold and flip the paper over
