Crystal Clear Periodic Table
The periodic table of the elements isn’t everyone’s cup of tea. But even if you aren’t a science geek, you have to admit that this is a pretty cool periodic table. Take a good look and you’ll find that samples of most of the elements are contained within the see-through table. The only elements that are clearly missing are the ones with the radiation symbol on them because no one wants a piece of radioactive plutonium hanging on their wall.
