Mega Menger

"A Menger Sponge is a three-dimensional fractal, which can be made by taking a cube and cutting out a square section through the centre in each of the three directions; then each of the resulting smaller cubes is cut out in the same way, and so on until you've removed infinitely many pieces." The resulting object "has zero volume but infinite surface area!"

Edinburgh University School of Maths is helping to build the biggest cardboard fractal ever. Our outreach team think this is a great use of cardboard, glue and time!
