Sevirium

Yep it's a soda bottle preform. Sorry, I'm used to write petling and totally forgot hat the term is only used in german speaking countries.

Made this head for one of my caches. The Coordinates for the next waypoint are inside a petling that's on the inside of a plasic bone. The bone is then pushed into the throat from it's bottom.

Any Breaking Bad fans around here? http://puu.sh/4ifgE http://puu.sh/4iffn Cache name is "Can't find it? Better call Saul!" and has a chemistry themed riddle to solve.
