Elongated Balloons (100 pcs)

A pack of 100 elongated balloons for a wide range of teaching experiments and demonstrations. Inflated to a narrow, tubular shape, they are handy wherever airflow and pressure are put to use. In physics they can drive an air-track glider (item 194505) to study motion with almost no friction, letting pupils analyse force, acceleration and patterns of motion, and they also serve in experiments on air pressure, sound and volume. Their versatility makes them a simple but effective aid across many lessons.
