1st. Take a Coke bottle and cut the top off.

NEAT TRICK: If you turn your canned air upside down and spray, you get a blast of frozen air (please don't get technical on this wording). If you spray your hot glue once you applied it with this method, it helps to set your hot glue quicker. I didn't spary much. Just a quick blast to hold it in place to keep it from dripping or running. Plus I am impatient and didn't want to wait for the glue to cool on its own.
