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

It's tempting to call the Rattleback a toy, but it's so much more than that. I got one a couple years ago, but someone else wanted it. So I treated myself to the Collector's Edition metal alloy version. And I also got the bag of 10 plastic ones, to give away. I can't wait until my grandson is old enough to appreciate it. Initially there had been a packaging error; Magic Makers more than made up for it. I'm quite pleased. Five stars!

This will keep you entertained for hours. Works great. Kids play with it, husband plays with it, guest see it and wonder what it is and play with it.

Does exactly what it says. Spin it one direction, it keeps spinning. Spin it the other, and it stops, wobbles for a second, and makes a half to three quarter turn the other direction and stops. Gave it to my MIT scientist spouse, and she said it was obvious that the bottom was slightly asymmetric, but said it would take too long to explain the math to me.

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.

Initially, no one believes the spinner will really do what you tell them it does! I love the look of shock when people see me spin it, and it goes on forever, and when I let them try, it not only stops, but then rotates in the reverse. My wife works in an elementary school and this is on her desk. It’s great for confounding children and adults alike. When their children look up, expecting her to say” it’s magic, that’s why” she looks them in the eyes, and simply says” it’s science, fun, ha”

muy bueno

not sure if the shape is quite right or maybe the mass and metal but it does not work as well as the plastic ones. works ok on harder surfaces (glass or metal) but not on my wood desk/tables.

Been searching for a metal rattleback for a very long time. Plenty of wood and plastic ones on the market, but this one is both literally and figuratively METAL. Very happy with it. Has a very nice smooth finish to it and works exactly like a rattleback should. Other info: It rattles back in the counterclockwise direction. The product description on this Amazon listing AND the product card that comes with the product don't say what kind of metal this is made from. Some other reviewers say this is steel, but it is very lightweight and non-magnetic so I suspect it is aluminum. I could be wrong, but this is just for info.

Buena calidad, cumple con la descripción y cumple con las expectativas.

Fantastic chunk of metal that does exactly what it’s supposed to. Spin it clockwise and it slows, rattles, and changes direction! Love it almost as much as my kid does!

C'est ce à quoi je m'attendais, il est pesant en main et agréable à manier. Environ 10 cm de long Un peu cher mais considérant les prix pour ce genre d'objet, ce n'est pas si pire Une belle addition à ma collection What you would expect, hefty and satisfying to handle, 10 cm in length A bit pricy, but that's expected considering this type of product Good buy, would recommend if you are into that type of object

Mezmermizing demo!

Will not turn to other direction after I turn clock wise. It just stopped even on a smooth surface.
