The second Wednesday in October is International Top Spinning Day. 10 things you might not know about spinning tops:
- Spinning tops are among the oldest recognisable toys found by archaeologists. They seem to have been invented independently by every culture in the world.
- A clay top unearthed in Iraq was dated to 35th century BC—nearly six thousand years ago, and there was one in Tutenkhamen's tomb dating back to 1300BC.
- Early tops were made from fruits, nuts and seeds.
- The laws of physics explain why an object that would normally fall onto its side remains upright while it is spinning. The motion of a top is described by equations of rigid body dynamics, specifically the theory of rotating rigid bodies. A spinning top is held upright by angular momentum. They eventually slow down and stop because of friction against the spinning surface.
- In the 8th century BC, the poet Homer mentioned tops in the Iliad: "Ajax caught up [a stone] and struck Hektor above the rim of his shield close to his neck; the blow made him spin round like a top and reel in all directions."
- In ancient Rome, a four sided top was used in gambling games. Each side was marked with a letter: A for Aufer meaning "take", D for Depone meaning "put down", N for Nihil meaning "nothing" and T for Totum meaning "all" meaning the player wins the whole pot.
- In New Zealand, Maori people made tops from gourds which made a wailing noise when they were spun. They were used in ceremonial mourning of the dead or to avenge a defeated clan.
- Cyclosa turbinata, a type of Spider, is named after the Latin for spinning top, because it is shaped like one.
- Two scientists called James David Forbes and James Clerk Maxwell experimented with spinning tops to see what happened when the movement of a top blurred its colours into one. Some of their observations contradicted what we know about colours, for example, they observed that "Blue and Yellow do not make Green, but a pinkish tint."
- If you want to celebrate International Top Spinning Day, here's how you do it. The aim is to get least 10,000 tops spinning around the world, so get a group of people together and spin some tops. Take pictures and email them to the Spinning Top and Yo-Yo Museum in Wisconsin, or share them on social media, #TopSpinningDay.
