AP5930 - \$10.10
Your students can use this ingenious pressure bottle to discover basic gas laws and properties of air. The pressure bottle is an ordinary 1-L soda bottle with a tire valve mounted in the cap. When the cap is in place, the bottle can be pumped up just...
AP4638 - \$40.00
Dramatic demonstration showing the force of air pressure that your students will remember for a long time. Simply hook up the hemispheres to a hand vacuum pump, an aspirator or vacuum pump and evacuate the air. Close the valve and let the pulling begin!...
AP5661 - \$19.05
An economic version of the classic force of air pressure demonstration. Air is removed by simply pushing the two rubber plungers together. Once they are together, your students will be amazed how difficult it is to pull them apart! Have students design...
AP7102 - \$4.65
Demonstrate the elasticity of gases using this simple instrument. Set a volume of gas in the piston, then use weights to pressurize the system. As the weights are added, the volume of gas is decreased. Students plot volume versus pressure to approximate...
AP9022 - \$17.45
Demonstrate the elasticity of gases using this simple instrument. Set a volume of gas in the piston, then use weights to pressurize the system. As the weights are added, the volume of gas is decreased. Students plot volume versus pressure to approximate...
AP4695 - \$11.45
Here's a forceful demonstration-over 1,800 lb of force! This demonstration will convince students that air exerts significant pressure. Simply place about a centimeter of water in the bottom of the can and heat it until it boils and steam comes out...
AP4713 - \$28.05
Simple, yet very dramatic. A thin white pine stick is placed over the edge of a table. A sheet of tissue paper is placed over the stick and spread out on the table. When the overhanging portion of the stick is hit sharply with a hammer it breaks. The...
AP9223 - \$17.15
Demonstrate the effect of pressure on a volume of gas. This easy-to-use apparatus is made of a 10-mL calibrated plastic syringe, a piston supporting a metal hanger, and a pinch clamp. Students produce a graph showing the relationship between pressure...
AP9292 - \$10.45
Truly a classic demonstration. Your students will be fascinated by the drinking bird that doesn't know when to stop. Teach thermodynamics and pressure, and have fun at the same time. ChemFax instruction sheet provided.
AP4531 - \$140.20
Unique device shows the relationship of pressure to temperature of a gas, allowing students to determine the value of absolute zero. The bulb is immersed in hot water, cold water, and a dry ice-acetone mixture. Temperatures and pressure readings are...
AP5882 - \$42.80
What does atmospheric pressure really feel like? This one inch square steel bar, weighing 14.7 lbs. and over 52 inches long, will literally drive home the point! Students will be amazed how much the bar weighs when they lift it. They will be even more...
AP6769 - \$45.10
Dramatically show that pressure is a force per unit area with this familiar demonstration. Place an inflated balloon on a wood block full of sharp nails. Add a 1000-g mass to the “floating” board on top of the balloon and amazingly the balloon does...
AP6884 - \$68.05
Bicycle pumps have several applications in a physical science classroom. The hand-held bicycle pump is an excellent and inexpensive choice for pumping up water rockets. Use the Bicycle Pump with Gauge and Release Valve for precise quantitative pressure...

AP6936 - \$29.25
Dramatically show atmospheric pressure in action! Use atmospheric pressure to pick up a lab stool, or to make a deceptively ordinary rubber mat nearly impossible to lift off a table. Simply place the Pressure Mat in the center of the seat of the lab...
AP7205 - \$46.35
Open up a world of understanding regarding air pressure with this simple, clever device. Simply place the balloon into the opening of the Harbottle and stretch the mouth of the balloon over the mouth of the bottle. Blow into the balloon and, when it...
AP7201 - \$102.00
Engage your students with this all-in-one pressure kit! Four hands-on lab activities allow students to explore the fundamental principles related to pressure. Students experiment with mini Magdeburg hemispheres to feel the strength of atmospheric pressure....
AP7213 - \$13.75
Amaze your students with the force of air pressure! This student lab kit dramatically demonstrates the force of air pressure using mini Magdeburg hemispheres. Simply press two Magdeburg hemispheres together until they stick, then hang them from a support...
