A screw is driven into a wooden plank, and then a car tire rolls directly over it.

The video shows a close-up of a screw puncturing a wooden plank, followed by a car tire rolling over the screw. Then, the tire is shown with the screw embedded in it. A person uses a tool to remove the screw, and then inserts a tire repair plug into the hole. The process is repeated on another tire, and finally, the repaired tire is shown inflated and intact.
