The impossible braid by Martin Gardner

The neeklace of leather is braided without loose ends!

Martin Gardner discovered this apparently impossible braid without loose ends.  Our colleague Nelo, member of «Divermates», gave us a rubber model during the last congress XVI JAEM in Palama de Mallorca.

Above you can see a necklace of several Garnder’s braids (with 12 crosses each) made with leather. We hope you can make one for your neck, hair (as the one below), wrist or ankle!
