Free Fall Tubes. A set of 2 glass tubes under a vacuum that contain pieces of a feather, paper, and metal. Size 40 x 750mm. Made by Narika Corporation.

Visualize Free Fall Motion with Atmospheric and Vacuum Tubes: This set includes two glass tubes—one under atmospheric pressure and the other in a vacuum. Both tubes contain identical samples of a feather, paper, and metal, making it easy to compare their behavior during free fall under different conditions. Simple and Effective Demonstration of Physics Principles: Invert the tubes to instantly show the effects of air resistance on falling objects. The feather, paper, and metal fall at different rates in the atmospheric tube but descend uniformly in the vacuum tube, clearly illustrating the role of air in free fall motion. Pre-Sealed Tubes for Hassle-Free Use: The glass tubes are sealed and pre-filled, eliminating the need for additional preparation or equipment. This allows for quick and efficient demonstrations, perfect for classroom settings.
