I was getting ready to turn on the fiber optic tree, had my 510 in my other hand (next to the branches). The tree was plugged in, just needed the switch turned on. Before I had a chance to flip the switch "on", the tree lights started glowing faintly and my e-cig got RED hot. I have no idea why this happened, but won't have my 510 near the tree again. Anybody know what caused this? The 510 was inside a tootbrush holder stand (metal) that I keep it in when it's on my desk, so I couldn't have pressed the manual button. The tree & the e-cig were turning each other on (oh my!).
