You probably don't need us to tell you that glue sticks are a nightmare in the classroom. Kids throw them around the room, remove the lids and hide them somewhere only they know, and they dry out quicker than you can say 'sticky.' But if you're looking to solve this problem and add some arts and crafts to your lessons, this teacher hack will definitely save the day. In fact, it's pretty awesome.
By lining a Tupperware pot with liquid glue, you can then top it with a sponge. When the kids want to use it, all they need to do is press the thing they want to stick onto the sponge and then lift it back up!
