In the video, a person is seen holding a piece of paper with the words "Happy Birthday" written on it. The person then takes a tube of glue and applies it to the paper. After that, they take a piece of glitter and sprinkle it onto the glued area. The person repeats this process with the rest of the paper, applying glue and sprinkling glitter until the entire paper is covered. The final product is a sparkling "Happy Birthday" sign.
