The box with schrödinger’s cat
Many people know the dilemma with the Schrodinger’s cat: she’s alive or dead. And at the same time.
Now you, man, there’s a chance to learn the fate of a cat with the help of this device. What is the practical purpose of the cat in the box? It’s very simple: we ask a question that can be answered in a binary manner (Yes/no). Open the door and watch as the slides change with the condition of the cat. At some point, the cat stops in one position. Or the poor cat is dead — no, alive and well the cat is «Yes.» So you got the answer to your question.
Of course, no living cat was not injured. Charging the device using 3 AA batteries.
Is this thing only $ 25. And you can buy it on thinkgeek.com
