Create a new 300mm x 300mm x 300mm cube which can twist or stretch elastically without breaking

• Use the same material in the original cube (obvs)

• Decide how to apply the load horizontally at one or two points

• The twist or stretch must be elastic (returns to the original shape once the load is removed)

• Include a way to measure how much it has twisted or stretched
