The "No-Touch" Zone: Never touch the metal nozzle or the glue immediately after it leaves the gun.
Drip Protection: Glue guns must stay over a silicone mat or a piece of scrap cardboard to catch drips.
The "Poke" Rule: Use a popsicle stick or a pencil—never fingers—to press two glued items together.
Unplugging: The last student at the station is responsible for checking that all guns are unplugged.
