The rabbit and the spinning egg
« on: May 09, 2013, 12:16:10 PM »

On the last newsletter from Grand Illusions this video from Tim's toy museum is featured.  I almost did not watch it as it seemed to be about a simple magnetic attraction between a bunny and an (Easter) egg . . . but boy was I surprised!

Magnetic Rabbit

I am amazed he can get such fast and continuous spin.  I need to do some experiments . . .

Thanks for the video, I have to search around for my plastic egg.  For the collectors, it is from Chadwick


It is never a bad idea to watch the toy videos from Grand Illusions.  I don't recall seeing this one posted on the forum before.

Thanks John for identifying the brand. I found one on Ebay and got it (just $0.99 . . . plus $7.99 for shipping by regular mail  ::) )

It arrived today and it was even better than on the video: instead of being attracted by the bunny, the egg is repelled.  As you approach it with the rabbit, the egg starts to spin at a good clip and will continue doing so as long as you chase it  :o

To me the effect was very surprising.  After some thinking and experimentation by replacing the bunny with a magnet, I figured out how it works. It is actually a very simple setup.  But there is genius in simplicity.  If you want to think about it, here is a clue: the egg always spins in the same direction, but that direction is determined by the type of rabbit.

Ahhh.....the type of rabbit!  Like the domestic or the wild rabbit?  Or the cylindrical or the compact rabbit?  Or the fully arched or the semi-arched rabbit?  Or maybe the jill or the jack rabbit?

 ;D  Like in left-handed and right-handed rabbits.  Considering that the rabbit can also be attractive or repulsive to the egg, there are 4 different types of rabbits.

Second clue: given a rabbit, you can modify the egg to be attracted or repelled to the rabbit, but you cannot change the direction it rotates; that is solely given by the rabbit.

Here is a different version of the bunny and egg replaced with a mirror and a ballerina. It's German but I found it on the French site toupie-shop.com mentioned by Hydrus.

For completeness, I'll add to this thread the Magic Top/Magische Kreisel, from Germany, or as the instructions said, Magneto No. 149, that is in Lourens Bas collection.

Contrary to the others, this is a true top (well, if the tip was more rounded it would certainly be).
