The stinging hurts, but the electricity is fun to play with. For example, for about 15 seconds(ish) after you go down the slide, you have the power to shock your unsuspecting friends. Plus, one time, i wondered to myself, "Since going down a slide generates electricity, if i were do go down the slide with an electronic in my hand, would it charge?" I tried this outlandish scheme hoping that it would work, but expecting it not to. So I took my dead DS (cause this was 2010 and it was hip), my charging cable for said DS, and all of my 4 friends and siblings down to the local playground. I got the charger in the DS, pressed the charger to the walls of the slide, and slid down the slide. I did this several times, and even let some of my friends take turns with the task. After about 5 slides i hit the power button. Sure enough, it turned on! For like, fifteen minutes, then it turned off again. It didn't last long, but it was glorious
