I dropped trou and left them in a heap on the bedroom floor, like the bachelor slob that I am. When I got out of the shower 15 minutes later, there were the pants still on the floor, with a cool-looking white glow coming out of the pocket. My L1p had turned on somehow even though there couldn't have been much of an impact, cushioned by the pants and all that. I'm not sure how it managed to do that. I'll have to watch out for that. This helps me remember why I like twisties.
