• Hands-On Physics Education: This affordable and historical demonstration helps students grasp complex concepts like atmospheric pressure and vacuum by providing a visual and interactive experience.
• Visual Atmospheric Pressure Demonstration: The Magdeburg Hemisphere allows students to see the effect of atmospheric pressure when a vacuum is created inside the hemispheres, showcasing how external air pressure prevents the spheres from separating.
• Perfect for STEM Classrooms and Homeschools: Ideal for both classroom and homeschool settings, this kit provides a simple and engaging way to teach physics concepts related to force, pressure, and vacuum.
• The two rubber discs are each 8 centimeters in diameter.
• Durable & Easy to Use: Made of high-quality materials, the hemispheres are durable, and simple to use, providing consistent results in classroom or science lab settings.

The Magdeburg Hemisphere is a modern take on the famous 17th century experiment. With the Magdeburg Hemisphere, you can demonstrate the force of air pressure without a vacuum pump. When the two cups are pressed together, the air is evacuated and a vacuum is created, separating the discs will be an interesting challenge for your students. This experiment is a classic in the field of teaching about vacuums. It comes as a pair of 2 discs, and includes instructions.
