The video begins with a close-up of a person's hand holding a small bottle of pH solution. The label on the bottle is clearly visible, and the person rotates the bottle to show the front and back. The person then unscrews the cap of the bottle and pours a small amount of the green liquid into a sink. The person then uses a dropper to add a few drops of the liquid to a cup of water, which is also shown in the video. The person's actions are deliberate and careful, ensuring that the pH solution is accurately measured and added to the water.
