Magic Makers The Rattleback, Physics Toy, Real Metal Alloy Collector's Edition

Pretty Cool

This trick is a solid piece of steel and is worth the extra money. The weight of the metal presents well and enables it to spin for a long time on a flat surface. Its secret is in slightly shifting the center of the weight on one side of the piece versus the other. It is almost imperceptible and is not noticeable when handed to audience members for a "look and feel" beforehand. Spin it counter-clockwise and it spins great. Spin it clockwise and it shakes, stops, then starts spinning counter-clockwise. It's a realistic and dramatic motion that can be easily exploited. Lastly, a warning: if you are someone who can really make objects move, DO NOT purchase this product. It will completely destroy your credibility if people one day find out this is a trick.

It is a nice product. It seems to work well. Rattlebacks are really amazing. They are simple, yet exhibit a very unexpected behavior. It is easy to get plastic rattle backs. but metal ones are hard to find.It would nice if the vendor would say what the metal alloy was. It would also be nice if they made them in a larger size.

Fun to watch it reverse directions. We’ll-machined

Good Quality!

It is a good rattleback because it is made from metal

I ordered the silver edition and they sent me the gold edition. Additionally it has a very large scratch right on the top.Also the quality of the "rattleback" doesn't seem very good. No matter how much or how little I spin it counterclockwise it shakes and basically comes to a stop instead of spinning back the other way.I bought this as a gift because I thought it would be super cool but now I am not so sure.

Rattlebacks are really neat oddities, with their seeming disregard for (near-)symmetry and angular momentum. They're not hard to find in plastic, and those are cool to have around, to be sure, but surprisingly hard to find ones in metal, for that heavy, satisfying feel. Makes for a much more dignified desk toy or living-room hutch knickknack. This one is the "usual" size and shape (whatever that is), does its job of spinning and not-spinning and unspinning very well. I don't know what it's made of; the description says "Metal Alloy" so I assume it's not aluminum or something. I can say that it is _not_ magnetic, which I consider a good thing (so you can experiment with sapping its momentum while spinning with eddy currents.)
