AutoSTEM Drawbridge construction tutorial

The Drawbridge is a toy bridge that can be raised to allow passage of a ship having masts too tall to pass under or to defend the entrance of a medieval castle. It is made from double-wall corrugated cardboard (from a big parcel), a wooden skewer, and string. The toy can be used in many ways and opens up a number of subject areas for further learning.
