I know my kids would have a lot of fun playing with this project from instructables user ‘walkalongaviation’. The glider works best indoors, so it’s perfect for those rainy [or just too hot] summer days.

This instructable shows you how to make a walkalong glider by thermoforming a styrofoam sheet. The foam sheet used here was obtained from the Owens Corning Raft-R-Mate product available in the insulation department of most home building supply stores.
