The video shows a close-up of a piece of paper with handwritten notes. The paper has three columns with the words "Water," "7%," and "Bleach" written at the top. The first column has the number "7" and "1%," the second column has "4.76%" and "2.52," and the third column has "93%" and "2.52." The handwriting is in blue ink, and the paper appears to be lined.
