Dried up glue sticks
Does anyone know if those little glue sticks in tubes can be revived? It's weird, I opened several packs and they are all dried. These are not some I recently purchased, but have had a little while. However, the packages had not been opened. Even though they are fairly inexpensive, kind of aggravated me that they would be 'ruined'.
I googled and didn't find anything there, and just thought someone here might have a miracle tip of some kind :-)
Thanks so very much!
