Quantum Superpositioned on Your Shirt
This might not be Hello Kitty. It might be Goodbye Kitty. We cannot possibly know without observing, and then we change the outcome.
What is it with cats and boxes? Despite all the talk of potentially dead cats, Schrödinger must have been a fan of the feline. He knew the perfect container for a cat was a box. Dog, not so much. Cat? May never come out. Which is sort of the point of the thought experiment. The cat might be both there and also not, but we know the box will remain on your shirt as long as you take care when washing it. Cuteness guaranteed. Live cat, not so much.
"Hello Schröddy" in black with a white box and a red bow on a pink babydoll (fitted) t-shirt.
Note: Don't want to have to explain this shirt to strangers? Fear no more! We now have free Schrödinger's Cat Pocket Cards to go with your shirt. They're perfect to print out and keep in your wallet so you can hand them out and make your escape while said strangers are busy reading.
