The video begins with two empty mason jars on a table. The jars have metal handles and are transparent. The first jar is filled with ice cream, and the second jar is filled with milk. The milk is poured over the ice cream in the first jar, creating a layered effect. The second jar is then filled with coffee, which is poured over the milk, causing the milk to rise and mix with the coffee. The video ends with the two jars filled with the layered coffee and milk, and a striped straw is inserted into each jar.
