About This Product
In air, a light object can lag behind a heavier one as both fall through the tube. Once a vacuum pump has drawn the air out through the stopcock, objects of different weights fall at the same speed, showing that air resistance, not weight, caused the difference. This version is the tube alone, for laboratories that already have a cast iron base stand to hold it.
