A split screen showing two methods of sealing a paint can, one marked with a red X and the other with a green checkmark.

The video is split into two halves, showing two methods of sealing a paint can. The left side shows a person incorrectly sealing a paint can by just pressing the lid down with their hand or hitting it with a rubber mallet. The right side shows the correct method: covering the rim of the can with plastic wrap, then placing the lid on top and sealing it with the rubber mallet. The paint can is light green with a white label that says "PAINT" and "ONE GALLON". The video demonstrates how to properly seal a paint can to keep the paint fresh.
