Comments about Arbor Scientific Newtonian Demonstrator:
It attracts people to play with it. I have to hide it for demos only otherwise kids are always playing with it.
Comments about Arbor Scientific Newtonian Demonstrator:
This is a large scale demonstration that can sit on a demonstration table for a typical classroom (20-25 students). I would not use this for a college lecture hall unless you could video tape it and display the video on an overhead projector. Some colleagues and I are planning on designing one of these deomonstrations using steel cable and 11 lb bowling balls!!
Comments about Arbor Scientific Newtonian Demonstrator:
Because it wobbles, it does not maintain momentum very long.
Comments about Arbor Scientific Newtonian Demonstrator:
just as pictured
Comments about Arbor Scientific Newtonian Demonstrator:
Very easy to use especially with children. It also teaches kids Science.
Comments about Arbor Scientific Newtonian Demonstrator:
This was a gift for my 7 year old. He loved it. I am so glad that I did not buy one of the cheaper ones.
Comments about Arbor Scientific Newtonian Demonstrator:
I used this for a class demonstration, and it was very effective.
Comments about Arbor Scientific Newtonian Demonstrator:
I had a smaller one last year that was used so much that it actually broke. When I put this new one out for my students to play with (I keep science toys out for my students to mess with before and after class) they all flocked to it and all wanted to play with it (and I teach 8th graders). They LOVE this item.
Comments about Arbor Scientific Newtonian Demonstrator:
This was a gift for a friend who is leaving Cleveland. The Newtonian demonstrator not only shows an important concept in physics but screams "SCIENCE!"
Comments about Arbor Scientific Newtonian Demonstrator:
Very simple but effective demonstration of opposite but equal forces.
Comments about Arbor Scientific Newtonian Demonstrator:
Wonderful demonstrator to show Newton's third law of motion!
Comments about Arbor Scientific Newtonian Demonstrator:
Great demonstrator to all ages. I place it on an overhead projector and let the kids see the shadow of the metal balls colliding... they love it!
Comments about Arbor Scientific Newtonian Demonstrator:
I bought the demonstrator for a child. I liked the size and it worked well, but the finish of the balls was very dull like they had had a reaction with something. It may have just been this set, but I was only disappointed by that aspect.
Comments about Arbor Scientific Newtonian Demonstrator:
Remember to unpack it in the upright position...if not the balls get all tangled!
Comments about Arbor Scientific Newtonian Demonstrator:
This is the best Newtonian Demonstrator around. Most of the cheap demonstrators click for a few seconds before stopping. This one goes on for a very long time.
Comments about Arbor Scientific Newtonian Demonstrator:
Newton's Cradle is a wonderful demonstration of momentum and kinetic energy. Students love to drop the balls and become intrigued by the puzzel of its motion. It is a great summary of the conservation laws.
Comments about Arbor Scientific Newtonian Demonstrator:
Have to continue to monitor alignment as the balls slip on the nylon line. When alignment is correct it works well
