6) Or how about a tower of skeletal octahedra instead? They’re a great challenge to put together – although you might need an extra pair of hands! https://abs.twimg.com/emoji/v2/... draggable="false" alt="✋" title="Raised hand" aria-label="Emoji: Raised hand">https://abs.twimg.com/emoji/v2/... draggable="false" alt="🤚" title="Raised back of hand" aria-label="Emoji: Raised back of hand">

7) Paper not your thing? Pencils are? You’ll need a lot of them for the fantastically rewarding Hexastix!

See my #ArtfulMaths blog post here with excellent video instructions from @standupmaths: https://www.artfulmaths.com/blog/hexastix 

PS">https://www.artfulmaths.com/blog/hexa... elastic bands disintegrate so best use string instead
9) Explore the tessellating properties of A-sized paper and create some tetrahedron wall art.

For instructions see my #ArtfulMaths blog post here: https://www.artfulmaths.com/blog/tetrahedron-wall-art">https://www.artfulmaths.com/blog/tetr...

10) Light up your life with beautiful #origami cube lampshades! https://abs.twimg.com/emoji/v2/... draggable="false" alt="💡" title="Electric light bulb" aria-label="Emoji: Electric light bulb">https://abs.twimg.com/emoji/v2/... draggable="false" alt="💡" title="Electric light bulb" aria-label="Emoji: Electric light bulb">https://abs.twimg.com/emoji/v2/... draggable="false" alt="💡" title="Electric light bulb" aria-label="Emoji: Electric light bulb">

Use baking or tracing paper with LED bulbs or fairy lights.

10a) These instructions from @origamifolding make the Sonobe lampshade below https://origamitutorials.com/sonobe-cube-lamp-tutorial/">https://origamitutorials.com/sonobe-cu... Can you spot the Pythagoras’ Theorem proof?
11) Try some kinetic modular #origami and make Yami Yamauchi’s wonderful rotating Fireworks model https://abs.twimg.com/emoji/v2/... draggable="false" alt="💥" title="Collision symbol" aria-label="Emoji: Collision symbol">https://abs.twimg.com/emoji/v2/... draggable="false" alt="💥" title="Collision symbol" aria-label="Emoji: Collision symbol">https://abs.twimg.com/emoji/v2/... draggable="false" alt="💥" title="Collision symbol" aria-label="Emoji: Collision symbol">
