Would you believe that origami can stop bullets? The origami above does just that!

Why origami?

· Allows barrier to quickly deploy to complex shape

· Allows barrier to be compactly stored

· Allows for barrier to be manufactured flat

· For more advantages of origami in engineering, see our website: cmr.byu.edu

This Instructable will help you create your own paper barrier.

In the real barrier, the panels needed to be made of thick bullet-proof material so a variety of thick-folding techniques were used. For more information on the design, see this publication:

Step 1: Print

Print or copy the fold pattern onto a piece of paper. The base pattern is a modified Yoshimura crease pattern.

Step 2: Cut Out

Cut along the bolded outer edges of the square pattern.

Step 3: Crease the Pattern

Follow the guidelines on the sheet. All the dashed lines are folded one direction, all the solid lines are folded the other direction.

Step 4: Collapse the Pattern

Collapse each layer of the pattern from the top to the bottom. The edges should rotate inward as the pattern folds flat.
