Atmosphere Bar
AP5882
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 mor...

Collapsing Can Demonstraion
AP4695
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 o...

Breaking Board Paradox - Demonstration Kit
AP4713
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...

Investigating Pressure Activity-Stations Laboratory Kit
AP7201
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 pre...

Pressure Bottle
AP5930
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...

Pressure Mat - Demonstration Kit
AP6936
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 ...

Up, Up and Away - Hot Air Balloon Student Activity Kit
AP6310
Up, Up, and Away—Fill the sky with colorful hot air balloons! Each student group will construct and launch their own giant hot air balloon. Students will learn how hot air balloons lift from the ground, stay afloat and eventually descend. A unique ba...

Pneumatics
AP8195
Explore functioning air compressors, pneumatic valves and cylinders with this hands-on kit. Includes a compact and powerful compressor to supply compressed air to the models. Build eight different working models: double sliding doors, scissor l...

Boyle's Law Apparatus
AP9223
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...

Absolute Zero Device
AP4531
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 ...

Elasticity of Gas Apparatus
AP9022
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 approxim...

Mini Magdeburg Hemispheres- Student Laboratory Kit
AP7213
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 sup...

Magdeburg Hemispheres
AP4638
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 beg...

Magdeberg Hemispheres, Rubber
AP5661
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 desi...

Harbottle
AP7205
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 ...

Bicycle Pump, Hand-held
AP6910
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 pressu...

Bicycle Floor Pump with Gauge and Release Valve
AP6884
