I don't have much information about this lamp design. But it appears that dropping a steel marble in the top activates the power switch. It takes about 21 seconds for the marble to spin in the video. Alternatively, I suppose, an impatient user could simply drop the marble down the hole.

Not to mention burns and abrasions from the friction. By the time you slid more than a couple of floors, the rubbing against the chute could create serious heat against skin.
I worry about someone twisting into the wrong position, getting stuck and others piling on top of him.
