This inexpensive demonstration can be used to illustrate many different scientific principles. When properly filled with a mixture of hydrogen and oxygen, a jumbo-sized plastic pipet bulb can be projected 20–30 feet across a classroom. The goal of this activity is to make a “chemical field goal” by sending the pipet bulb through the goal post on the opposite side of the classroom.
