Grade 7 and up. A simple, clever device to introduce air pressure. Simply place the balloon into the opening of the bottle and stretch the mouth of the balloon over the mouth of the bottle. Blow into the balloon, and, once fully inflated, stopper the bottom hole of the bottle. Amaze your students when the balloon stays inflated - no twisting or tying required! Fill the balloon with water to demonstrate the power of pressure! Makes an excellent visual aid for discussing pressure and its real-world applications, including vacuum cleaners, pumps, flight, weather, and even how we breathe! Includes 5 in. diameter glass bottle, rubber stopper, two balloons, and teacher’s guide with information and activities.
