With this little game you can test the intelligence of your friends, family, bar mates and colleagues. let them only see the card and ask if they think there exist a form that will fit in all three holes (not at the same time) and must touch all the outer edges. Let them think for a while and than show them the form and prove that it exists. Lots of fun. The card has the size of a credit card.
