Hot glue - does it expire?
Maybe not the best place to ask, because we use mostly school glue, but the other day I got out my hot glue gun for a repair on a Christmas wreath, and it seemed to take a forever for it to heat up -- not a big deal, it did, the glue was melting but then it didn't seem to hold anything. I did decide my gun was just too old now - it must be at least 20 years old, which means the glue is too. There seems to be a lot of it (some is in a House of Fabrics bag to give you a clue how old it is). But my DH thinks I should give it to a thrift store, I believe it belongs in the trash. What would you do?
