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.
