R.Buckminster Fuller was a great engineer and inventor. He did a lot of work with geodesic domes, but he didn't invent them. Geodesic domes are domes made out of triangles. Triangles are very strong, so they hold up well under pressure unlike squares that tilt under pressure. I made mine out of toothpicks and clay. It is strong enough to hold a banana, but only for a little while before collapsing. I suggest you make one. It is a lot of fun. Happy building.
