Fluorescent Worms Polymer Chemistry Kit

This polymer kit allows students to learn about polymers and cross-linking by creating fluorescent gel-like worms. Students add a sodium alginate solution to three calcium chloride solutions, each containing a different fluorescent dye. After a few minutes, the liquid alginate forms into gel-like polymer strands that glow red, blue, and green under a black light. The kit includes 6g sodium alginate, 1L each of three calcium chloride solutions with fluorescein, rhodamine B, and quinine sulfate respectively, 3 empty bottles with flip-top caps, and 6 forceps. Materials are sufficient to make several dozen polymer worms. Containers for the calcium chloride solutions (such as beakers or plastic trays) and a black light are needed but not supplied. For laboratory use only.
