Wishlist Wednesday: Radioactive Coasters. Geeks & Nerds of the world UNITE!

Finally! It's March! I've never cared much for February. Now it's March and I can start looking toward spring (not that we ever had a winter down here in South Texas this year though). It's Wednesday, so that means it's Wishlist Wednesday time! This is the part of the week where I find something random on Amazon that I just HAVE to have! This week:
WHOA. Y'ALL. I NEED THIS. I NEED IT.
Featuring the atomic number and isotopic mass of the most stable or common isotope for their respective radioactive elements, these pressure-sensitive coasters light up when you place your drink on them.
Choose from red Radium-226, blue Plutonium-244, green Uranium-238, and orange Thorium-232.
Each coaster requires 2x 'CR2032' batteries, which are included.
Which radioactive element is your favorite?
