Abstract: A lollipop stick includes a plastic stick body having a longitudinal receiving cavity formed therein and a fluorescent layer thereof, a breakable airtight tube disposed in the longitudinal receiving cavity and having a first solution contained therein, a second solution contained between the plastic stick body and the breakable airtight tube, and a conjunction structure connects an end of the plastic stick body and being concave-and-convex for combining with esculent sugar cookies. Whereby the breakable airtight tube is fractured while the plastic stick body is bent, the first solution mixed up with the second solution and results into a chemiluminescence reaction by exciting the fluorescent layer thereof.
