  • Solids of Constant Width
  • Gaussian Gun

The first one we got didn't work at all because the parts didn't fit properly. The replacement is better but feels as though it will become loose if used too much.

You do seem quite a bit more expensive than the average scientific toy shop.

Russian Rattleback

Works well as advertised and has enabled me to understand its behaviour in terms of the third derivative of position with respect to time, jerk energy in other words.

Russian Rattleback

This was the second one I had bought. This was a gift for a friend. Although the reversal of spin direction happened, It was not quite as strong as with the first one. Some problems with quality control?

This is not as pretty as some larger Rattelbacks that I have found. That said, the movable weights provide a nice way to explain why it works.

A great 'toy' that we use to initiate thinking about the laws of motion.
