Clever Fisherman

There is an aquarium in the room, with bars on the top so players cannot fit their hands inside. On the bottom, there is a small toy fish with a key on its side. Players have to get the fish out but all they can find is a broken fishing rod (a part of the handle). Instead of looking for other parts of the rod, players have to put the handle (with an RFID item hidden inside) in a specific place to trigger the RFID sensor and activate the pump. When the water level in the aquarium reaches the bars on the top, the pump stops and players can get the fish with a key. Electronics needed: 🃏 RFID sensor, 🧩 Universal puzzle controller, 💧 Pump output set
