Show your students that objects in a vacuum fall at the same acceleration regardless of their mass. Evacuate the tube using our vacuum pump and amaze your students as they watch a feather and metal disc fall at the same rate. Or run vacuum tubing from the evacuated tube under water and open the stopcock; water bursts into the tube, creating a beautiful fountain. Apparatus includes acrylic tube, end plugs, metal disc, feather, vacuum stopcock, and tripod base.
