How to Build a Geodesic Dome?

, ,

Using gumdrops and toothpicks, make your own geodesic dome.

Geodesic domes are extremely rigid. Multiple interlocking triangles form incredibly strong structures. To deform or buckle a triangle you have to compress or stretch the lengths of the sides, which is hard to do as they support each other.
