The video begins with a close-up shot of a beaker on a table. A person pours a clear liquid into the beaker, which is already filled with a green liquid. As the clear liquid is poured, it begins to react with the green liquid, causing it to change color. The liquid in the beaker turns from green to orange and then to a light green color. The reaction continues until the liquid in the beaker is a uniform light green color. The person then stops pouring the liquid and sets the beaker down on the table.
