The magic of science!
Incredible magic! Or is it science? How the heck does this one work??!!
You don't even have to know how this one works- it just does! Newton's Nightmare must be seen to be believed! An amazing display of gravity defied! Perfect for classroom use! If you can drop the weight into the tube, you can do the trick!
All you have to do is drop the brass weight through the aluminum tube. It zips right through, of course, falling into the spectator's hand. But now, at your command, the weight is again dropped through the tube, but now it falls in slow motion through the tube! YES, REALLY!!
