Copy and paste both of the following nets onto thick cardboard. Carefully cut out both figures and lightly score along the lines joining each pentagon.
Gently fold inwards along the scored lines for each net, creating two “bowl” like shapes
Finally, place the two nets on top of each other in such a way that:
- Both of the “bowls” face each other.
- They are offset so that there is an equidistant “lip” around the outside as shown below.
For the final step, hold both nets flat with one hand, and use your other hand to interweave an elastic band alternately above and below the exposed “lips” as shown in the diagram above. The key here is to make sure that the elastic band is not too strong and not too weak.
Once you have successfully interwoven the elastic band slowly release your hand from the nets and let the elastic band do its job……..and watch as before your very eyes up pops a dodecahedron!
