Microwave Origami: an automated paper craft made up in a microwave oven. 

POPAPY is an instant paper craft that is made up in a microwave oven. With ordinary paper and designed special sheets, we can get 3D paper craft by 1-minute microwave cooking.

The special sheet is made from a combination of two materials, a heat-shrinkable sheet and a microwave-safe aluminum sheet (susceptor). The aluminum sheet absorbs microwaves and provides heat energy to the heat-shrinkable sheet efficiently. Then the shrinking sheet bends and folds the paper. We established a design method for the bending angle and bending timing by changing the size of the two materials.
