A 'Rattleback' is a specially shaped spinning top. It has a semi-ellipsoidal rounded top which will rotate on its axis but only in a preferred direction. If however it is spun in the opposite direction, it becomes unstable, starts to rock or "rattle", then the spin comes to a stop, whilst the rocking continues and then reverses its spin to the preferred direction.
Fascinating to watch!
This spin-reversal appears to violate the law of the conservation of angular momentum. Find out more about this fascinating shape here:

I make a wooden rattleback
( a rattleback may also be known as anagyre, celt, celtic stone, rebellious celt, rattlerock, spin bar, robinson reverser, wobble stone, wobblestone, keltischer wackelstein, wackelholz )
A nice toy with a base shaped like the hull of a boat. I only spins in one direction. When you spin it the other way, it turns a few times before it start to rattle up and down. Finally, it starts to spin in the opposite direction.

A rattleback (also known as a celt or a wobblestone) is a type of spinning top that will spin in one direction, but when you spin it the other way it will slow down until it stops, wobbling along its length, and will then spin in the opposite direction.
Originally seen as mysterious, they are now regarded as an interesting piece of physics. One of the original papers explaining how they work was presented at the Royal Society in London in 1988.

A rattleback is a semi-ellipsoidal top which will spin on its axis in a preferred direction. If spun in the opposite direction, it becomes unstable, "rattles", stops and reverses its spin to the preferred direction.
This spin-reversal motion seems, at first sight, to violate the angular-momentum conservation law of physics. Moreover, for most rattlebacks, the motion will happen when the rattleback is spun in one direction, but not when spun in the other. Some exceptional rattlebacks will reverse when spun in either direction. This makes the rattleback a physical curiosity that has excited human imagination since prehistorical times.[citation needed]
Rattlebacks are also known as an "anagyre", "celt", "Celtic stone", "rebellious celt", "rattlerock", "spin bar", "wobble stone" or "wobblestone" and by the product names "ARK", "Bizzaro Swirls", "RATTLEBACKS", "Space Pet", and "Space Toy".
Archeologists who investigated ancient Celtic and Egyptian sites in the 19th century found celts which exhibited the spin-reversal motion. The antiquarian word "celt" (the "c" is pronounced as "s") describes adze-, axe-, chisel- and hoe-shaped lithic tools and weapons.
