Up-pops : Paper Engineering with Elastic Bands

The ten basic paper engineering mechanisms shown in this book have an almost explosive quality.

Each 'up-pop' folds flat, but when it is eased out of its envelope, or restraining sleeve, it suddenly and unexpectedly jumps into a 3-dimensional shape.

This element of surprize is most attractive and suggests all kinds of imaginative designs.

The motive power for each mechanism is provided by a single elastic rubber band.

With each example there are useful notes about the mechanisms and suggestions for the further development of the ideas to create original designs.
