Did you know hexagons are geometry’s powerlifters? On this episode of Stem At Home we’re going to test the strength of a hexagon as we build a truncated octahedron.
Cut 10” of string and tie a knot in each end of the string.
Put push pin in one knot on the string and pencil in the other.
Put the push pin in your piece of cardboard and use the pencil to draw a circle.
Insert pin in to hole and make mark on circle. Move pin around circle from mark to mark.
(we make this easy to understand in the video).
Use your straight edge to draw out a hexagon from the marks on the circle.
Cut out the hexagon with your scissors.
Use the edge of the hexagon to draw out a square. Cut out square with scissors.
Use the cut-out square and hexagon to draw the pattern for your truncated octahedron on a poster board (don’t worry, we’ve got the pattern here for you to reference).
Once you have cut out the complete pattern, use your straight edge to bend the corners.
Use tape to hold together your truncated octahedron.
Break out some thick science books and see how much your hexagon can hold.

Congrats on building your truncated octahedron. We hope you enjoyed learning about the strength of hexagons, a shape that informs our design process every day! Be sure to share yours #StemAtHome.
