The video shows a cartoon mouse wearing glasses and a bow tie, sitting at a table with a flask of green liquid. The mouse is holding a test tube and a burner, and he is seen pouring the green liquid into the flask. The mouse then lights the burner, causing the liquid to heat up and produce a large explosion. The mouse is shown with a surprised expression on his face. The background shows a purple cat sitting on a green chair, watching the experiment. The table has an orange and a brown object on it.
