The mushroom model is powered by pneumatics. Pump the piston on the side of the model and the mushroom lifts up revealing his eyes. Stop and the mushroom drifts back down to the box as the air leaks out of the box.

Download the model and lets get started making this fun and quirky model.

There are two version of the project in the downloadable file, colour and mono, pick the version to fit your needs. Print out the three parts pages onto thin card. 230 micron board is perfect for the job. You’ll need a few basic tools to make this model. Scissors, ruler, a sharp knife, some PVA glue and a glue spreader. Carefully score along all the dotted lines and cut out any holes before you cut out the parts form the sheet. Both these jobs are easier on a whole sheet. Cut and score as accurately as possible for best possible results.
