Coin and Feather Experiment with Vacuum Pump – Physics Science Kit for Gravity, Air Pressure, Newton’s Laws – STEM Classroom, Homeschool, Science Lab Equipment

This physics science kit includes a hand-operated vacuum pump and a coin-and-feather apparatus for demonstrating gravity, air pressure, and Newton’s laws of motion. Designed for STEM classroom instruction, homeschool science activities, and science lab experiments, it offers a hands-on way to explore core physical science concepts.

The coin-and-feather experiment uses a sealed plastic cylinder with rubber stoppers and a hose port for air evacuation. When connected to the vacuum pump, air is removed, allowing the coin and feather to fall at the same rate—demonstrating that in a vacuum chamber, mass does not affect free fall.

The vacuum pump features a pumping rate of 15 ml per stroke and can displace up to 725 ml of air. It includes a built-in pressure gauge (in cm and inches) and release valves for safe use. It also works with other science lab equipment such as the #4400 Filtering Kit.

An instruction sheet is included, making this an ideal educational science tool for physics demonstrations, air pressure experiments, and physical science activities across learning environments.

Complete Physics Science Kit – Includes vacuum pump and coin-and-feather experiment apparatus to demonstrate gravity, air pressure, and Newton’s laws of motion in a vacuum chamber environment.

Gravity Demonstration for Classrooms – Ideal for STEM classroom kits, homeschool science lessons, and lab instruction, showing how objects of different mass fall at the same rate in a vacuum.

Educational Vacuum Pump – Hand-operated pump displaces up to 725 ml of air at 15 ml per stroke; features built-in pressure gauge (cm/in) and release valves for use in air pressure experiments.

Interactive Coin and Feather Experiment – Demonstrates how removing air with the vacuum pump eliminates resistance, allowing the coin and feather to fall simultaneously—highlighting core physics and gravity concepts.

Instructional and Homeschool Ready – Step-by-step guide included for setup; suitable for science lab equipment collections in schools or home-based physics and STEM instruction.
