If you would like the alive kitty/dead kitty Schrodinger effect going on, please select "both kitties" from the drop down menu. You will save on postage costs this way as you will only be charged for postage for 1 coaster!

If you would only like 1, please select whether you would like an alive kitty or a dead kitty. Please let me know what background glass colours you would like in the "message to seller" field. Printing is only available in the red/brown colour shown.


I was both alarmed and appalled at the lack of listings when searching "Schrodinger" on etsy. Then I figured I might have spelled his name wrong. So I checked on wikipedia and lo! I was right the first time! And so the Schrodinger's coasters were born...

These are awesome. Not only because, well, they are, but also because it's one of the very few geeky ideas I've had which my husband didn't suggest first in some way! They're mine! All mine! tee hee hee! (Note to self, work on evil laugh)

When your glass is on the coaster, you can't tell if your glass is on a live cat, or a dead cat. Much like the cat in the box. If you've NO idea what I'm on about, go and read a quantum mechanics textbook. Or wikipedia. Either way... Then come back and marvel at how geektasticly awesomerific these coasters are! They're possibly even verging on nerdy. Oh yes.

Coasters are made to order in any colour, with any colour border, or no border if you'd prefer. But because the cat faces have to be smaller so they're covered by a glass or a mug, the border helps to fill the space a bit.
