|Testing the cards in a practice build|
Stand-up Mathematician Matt Parker, along with a team of volunteers are looking to build the world’s largest fractal, using over a million folded business cards.
A Menger sponge is a fractal based on a cube, which is made of smaller cubes, which themselves are made of smaller cubes, and so on - giving it the fractal property which makes it interesting to mathematicians - plus, it looks very cool. It’s possible to build a Menger sponge using pieces of rectangular card, using a simple folding technique and a little patience.

Matt, along with a collection of other mathematicians organising events around the world, is building a MegaMenger - a giant distributed fractal, composed of 20 smaller versions of itself. The Manchester build is one of over 20 all taking place during the same week, and if all of them are completed in time we’ll have built the biggest Menger sponge ever made. There’ll be live video feeds from all the other locations, so you can watch as everything comes together.
We’ll be building part of the whole MegaMenger fractal as part of Manchester Science Festival on 25th and 26th October, and we’re looking for keen volunteers to help us build it. If you’re free on either or both days and want to be part of the building team, email firstname.lastname@example.org and we’ll send you details of how you can get involved. We'll also provide you with training you will need.
"It turns out that building a Menger sponge is brilliant fun and very addictive"
