Gases & Liquids : Atmospheric Pressure

Demonstrating Atmospheric Pressure

101,000 Pa or 14.1 pounds per square inch. Most students are incredulous when told how much pressure everything on Earth (including their own bodies) are under every second of the day. Which is why it's important to be able to visually impart this concept with quality demonstrations and activities.

Enter the PASCO Atmospheric Pressure Demonstrator and Magdeburg Plates. Used individually or in conjunction they provide dramatic proof of the weight of our atmosphere and its effects.

Atmospheric Pressure Demonstrator

Reveal the full force of atmospheric pressure with this simple demo. Just place this rubber sheet on the smooth surface of an object and lift.

How it works: A partial vacuum forms under the Atmospheric Pressure Demonstrator when it is placed on a smooth, flat surface and pulled straight upward with the handle. The substantial pressure differential created means you can lift sizable objects such as boards, stools and more.

Magdeburg Plates

These two plates are a modern and versatile rendition of a classic demonstration: Air is evacuated using a syringe; no vacuum pump needed Two different "O" rings allow 2 different size areas Includes: Polycarbonate Plates (2) O-rings (2) Syringe (60 cc) Connecting Tube with one-way valve with inline connector for optional Pressure Sensor
