These are the kinds of things that teenagers find in abandoned cabins in the forest right before they get slaughtered. Touching one will certainly open a portal to another dimension that is filled with creatures beyond what our human minds can comprehend. Blood thirsty and hungry for power they will step into our world, devour our souls, and render our WiFi signals unusable.
Ok, none of that will probably happen unless either a.) you're house was built on an indian burial ground or b.) you seriously need your meds adjusted. But I say throw caution to the wind and welcome one of these Artifacts from Maximum Fluoride into your life. Worst case scenario is you have an awesome conversation piece that will make you feel like Indiana Jones. Best case is that you become some sort of supreme overlord that rules an army of the undead. Either way, pick one up when they go on sale at noon today from http://maximumfluoride.bigcartel.com/.
