Construct a free standing bridge out of spaghetti, strong enough to support a 1/2lb bag of sugar.
How does it work?
Bridges manage two important forces: compression and tension – pushing and pulling. Too much of either and they buckle or snap.
Why not take inspiration from these iconic bridge designs?
- Small rubber bands or bag ties
- 1/2lb bag of sugar
Think about bracing strands together for strength. Some shapes are better at absorbing loads – triangles are particularly strong. Rubber bands make for good junctions.
