No guarantee any of these ideas actually work!! Use caution! Chemical reaction in the stick, produces phenol as by-product. Keep mixture away from skin in case stick case splits or breaks. If spilled on skin, can cause reactions from skin irritations to vomiting and nausea. Not proven cancerous. Flush with soap & water or clear water in eyes. http://victorcab.blogspot.com/2008/09/what-is-glow-stick-top-10-things-to-do.html
