ALT A Challenge Card titled Geodesic Domes with text as follows: Designed by Hannah, Design engineer at Dyson The brief Using jelly sweets and cocktail sticks, make your own geodesic dome. Materials Cocktail sticks: 35 at 60mm long and 30 cut down to 54mm long. Jelly sweets Scissors (with adult supervision) The method Follow steps 1 - 6 in the diagram below. Key for cocktail sticks: dark line 60mm lighter line 54mm How does it work? Geodesic domes are extremely rigid. Multiple interlocking triangles form incredibly strong structures. To deform of buckle a triangle you have to compress od stretch the lengths of the sides, which is hard to do as they support each other. Design Icons 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.
