Okay...so I was goofing around with my plasma globe. My computer was in my lap at the time too. When I touched it, I felt a sting on my leg. Turns out that touching the plasma globe and something with a current running through it is a bad idea. Also, my mouse pad on my laptop wouldn't work for a minute when I accidentally touched the globe and the pad at the same time. My mouse just freaked out and didn't respond to my touch.
