DIY Tip of the Day: Free glue dispensers. Here’s a tip from reader Don Ayers. Fill snap-capped water bottles with glue and stick them upside down in a 2x6 into a hole that’s a smidgen larger than the cap’s diameter. Now you don’t have to wait for the glue to run into the neck of the bottle, and the cap will control glue flow. Be sure to snap the lid closed before returning the bottle to the base.
