So my santa gathered up a number of items for me. First up was a pen that contained the periodic table. It took me awhile to figure out that it didn't just say "Innovating science," and I had to pull it out. I confess, most of us chemists don't have the table memorized... just the parts we work with. Besides there's always one on the wall when we need it. Next up was the Vertical Vortex this is a pretty cool toy. What appears to be a set of rings, is actually one piece of metal looped upon itself so it can expand. It also rolls when expanded, which is really fun to play with. Lastly is a candle stick. Honestly I thought it was a conceptualized doctor's stethoscope, until i found the note on the inside of the box. So I busted out my black light to put it to the test. It appears to be lightly uranated glass. (uranium containing). The black light isn't the end-all-be all to see if it contains uranium... I'd like to get a geiger counter, but dont have one on hand right now. Regardless this is still a pretty cool set of gifts.
