I am absolutely thrilled about my Reddit secret Santa gift package. I got a gyroscope, a magnet-powered spinning top, a radiometer, a book on building your own low-temperature Stirling engines, a couple of books on backyard astronomy and a shot-glass from Texas! Wow, what a great day. Thanks so much to my secret Santa, you get 10/10 for effort and the same for performance. My girlfriend actually commented "she's better at buying you gifts than I am," which is quite amusing. In the video I also do a pretty average job at explaining how everything works, just for interests sake (it's Newton's third law, not second when I'm talking about the radiometer).

So again, thanks for the wonderful package.
