How Fast Is Yo-yo?

A yo-yo at the bottom of its string has its outer edge spinning at up to 18 km/h. The toy has been around since at least 500 BC in ancient Greece — making it one of the oldest toys still in widespread use today.

A 1932 patent describes the modern axle yo-yo. Before that, yo-yos had a fixed string, making the 'sleeper' trick impossible.

• Same pace as a galloping horse
• Around since 500 BC
