epoxy

Epoxy is a type of glue. It's special because it's really strong, so when you glue two pieces of a toy together with epoxy, it will hold really, really tight. To use epoxy, you mix together two special liquids so that they form a thick, sticky liquid. Then, you put this liquid on the pieces of the toy that you want to glue together. Finally, you press the pieces together and hold them in place until the epoxy dries, which usually takes a few hours. After it dries, you can't separate those pieces anymore, because the epoxy glue has made them superstrong.
