Using gumdrops and toothpicks, make your own geodesic dome.
How does it work?
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.
Richard Buckminster Fuller, inventor of the geodesic dome. He was inspired by beehives, fishing nets and other ‘networks’. Today there are more than 300,000 geodesic domes around the world.
