Folding Diagrams for the
Prayer Fold (Last 5 Steps) and
Waterbomb Base (All 14 Steps)
A traditional base, as diagrammed by Jasper.
The waterbomb base is a simple fold that takes 1-3 minutes to make.
This base is used in the waterbomb, iris, frog, and many other models.
A six inch (15 cm) square makes a 6 " x 3 " (15 cm x 7 1/2 cm) base.
The instructions are quite detailed. If they give you any difficulty, please
let me know.
An Outline of the Diagrams:
- If you want the colored side out
start with a square, colored side up.
Valley fold horizontally,
so that the top edge lines up with the bottom edge...
- ...valley fold in progress...
- ...valley fold in progress.
- Unfold, so that the colored side is up.
- Valley fold,
and unfold, vertically.
- Turn the model over,
so that the white side is up.
- Valley fold diagonally.
The two opposite corners will line up;
the crease runs from a corner,
through the center, to the other corner.
- Unfold, so that the white side is up.
- Valley fold, and unfold,
the other main diagonal.
- The white side should still be up.
Begin the "prayer fold":
Holding the bottom edge flat,
lift up the left and right sides...
- ...as you lift the edges, they will pinch together.
The top edge will lift up...
- ...bring the side angles in to the centerline...
- ...and flatten the model.
- The finished waterbomb base.
Steps 10-14 are called a "prayer fold",
possibly because the simultaneous inside reverse folds
bring the folders' hands together in a motion similar
to a gesture used in many prayers.
