I lead a Valentine's Day Party for 4th graders featuring many products from Grand Illusions. Magnetism, Electricity, and Chemistry are not just words of LOVE. The Guassian Guns were a favorite (we shot them down and around a Darda race track so we didn't lose the ball bearings). The kids loved experimenting with 2 Guassian Guns -- firing them towards each other, using differing numbers of magnets and differing numbers of ball bearings, etc.

I plan to amaze fellow U3A members with this at a future meeting of the Science and Technology Group.

Fab. Does exactly what it said it would. Fascinating.

This is one of the best demonstrations on conservation of energy I have ever seen. I am making a lab out of it requiring my students to calculate the magnetic field of the magnets based on teh change in momentum of the ball bearing. Thanks for having such a wonderful device.

Keeps kids amused.

Has caused great amusement.

Gussian gun is the real interesting experiment with the magnets. You can use few gussian guns together on one track to reach more power. Super!

Magnets are very strong, and metal components are very well made.

This is a very nice rendition of this effect.

Was smaller than I hoped it would be, though it was a extremely agreeable price.

Isn't quite as exciting as the video but fun.
