A man stomping on a floor that makes a loud squeaking sound.

The video starts with a man demonstrating a squeaky floor by stomping on it. He then goes to a store, picks up a tube of Gorilla Heavy Duty Construction Adhesive, and proceeds to apply it to the joists and subfloor from underneath. He uses a drill to secure the wood. The final scene shows him stomping on the floor again, which is now silent, and giving a thumbs up.
