Product Details

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 stand. Attach a spring scale to the bottom hemisphere, and pull down. Students will be astounded at the force required to pull the Magdeburg hemispheres apart! Quantitative measurements using the spring scale allow students to calculate the air pressure related to that force. Detailed student instructions and Teacher Notes are provided.

Complete for 30 students working in pairs. Spring scales (2000 g/20 N) are required and available separately.
