Crack the Safes Exhibition by Hands On!

Crack the Safes

Crack the SafesTry to open the safes by finding the correct permutations of numbers. Visitors using this exhibit are challenged to think systematically and mathematically about possible permutations. The more buttons there are, the more combinations of numbers can occur and the harder it is to "crack" the safe. The exhibit includes safes of three, four and five-button configurations.
