I found these wonderful "Tap-n-glue" caps for glue bottles in the School
Specialty catalog. They are bright red and very cheap (less than a dollar
each I think). You NEVER have to open or close the glue. You NEVER have to
unclog the glue! There is a nub on the end of the cap which opens when you
apply pressure, and closes when the bottle is upright. They are awesome, a
little noisy, but awesome! -Becca
