Because science is everywhere, this is a video of sulfuric acid being poured toilet paper rolls. First it turns yellow, the face melts off, then the paper turns to jelly. Then...the darkness comes. So, if you were ever wondering if you should soak your toilet paper in sulfuric acid before wiping your ass with it, the answer is a resounding 'Absolutely.'
Keep going for the video, the smiley face roll starts at 1:10.
Thanks to Dunc, who soaks his toilet paper in vinegar because actually I don't want to know why.
