In the video, a young boy is seen wearing a white lab coat and standing behind a table. On the table, there is a black tray with a bottle of soda and a bag of Mentos. The boy pours the soda into the tray and then drops a Mentos into the soda, causing a large eruption of foam to shoot up into the air. The foam is thick and white, and it covers the entire tray. The boy looks excited and happy as he watches the foam erupt.
