What we did:
Fill your bottle half full with hot water.
Pour a container of glue into the bottle and shake.
Drop in your buttons and glitter,
Tighten lid (maybe even glue it on), shake.
We learned that the more glue you use the slower your buttons will drop. We used a whole bottle of clear school glue. And we learned to be careful not to add too much glitter, it didn't take much for it to become very hard to see the buttons at all.
