Replica of the Chernobyl AZ-5 reactor scram button as seen in the HBO series, using a genuine Soviet USSR red button. Feel what it was like to press the actual AZ-5 button at Chernobyl that made the reactor melt down! No electronics but you could add a siren, use it to switch on your computer, or connect it to an RBMK reactor and initiate an emergency shutdown (but remember to press it for the full 3 seconds).
