This balloon stays inflated without a knot!

Discover the prairie dog balloon experiment! See how pressure, volume, number of gas and air molecules, and temperature affect the size of the balloon in this exciting experiment. Notice how the state of the molecule also affects the pressure. Increase your depth of understanding for gas laws. For an added challenge try and draw a particulate diagram that shows how the gas molecules and their states account for the observed phenomena. For an even greater challenge try and graph what the pressure, volume, number of gas molecules (air and water), and temperature--do as time progresses. I hope you enjoy!
