A bottle launcher usually uses pressurized air and water to shoot a bottle high into the air. Usually built with easily found supplies, this project is suitable for both fun and education, though it will take some handiness with PVC piping. | A bottle launcher usually uses pressurized air and water to shoot a bottle high into the air.

#Understand what is going on. As the air pressurizes the bottle and launcher and is then released it creates an action force blowing the escaping air down. In turn this creates an equal and opposite force for the bottle to go in the other direction, upwards! This is because of Newton's Third Law of Motion. Increasing the pressure inside the bottle increased the thrust (Newton's Second Law of Motion). The water is inside the bottle to add velocity, as the water is heavier than the air so as the air pushes the water out first on launch your bottle will fly further.<ref>https://www.youtube.com/watch?v=gyOzvqmUs4c</ref> | #Understand what is going on.
