The very first safe belonged to Pharaoh Ramesses II in
the 13th century BC, was made of wood and locked using
a pin tumbler system. Safes and vaults have come a long
way since then! Discover how logic gates control the
opening of the safe, where without the right combination
of actions, the safe will remain locked! This hands-on
project teaches problem-solving, sequential thinking, and
mechanical-electrical integration, giving kids a tangible
reward at the end: a safe they can operate and proudly
show off.
