A YouTuber sets out to answer the question of whether it's possible to dice a tennis ball using a tennis racket. The host creates custom rackets with razor blades and music wire, and uses an air cannon to propel the tennis balls at high speeds (up to 560 miles per hour). After several tests, the host successfully dices a single tennis ball, and then goes on to dice two and three tennis balls at once. The experiment also leads to the development of a device that can cut French fries at high speeds, and the host tests the air cannon on a watermelon.
Here are the key facts extracted from the text:
1. The world record serve speed in tennis is 157 miles per hour.
2. Tennis balls can compress a ton before they pop and are super elastic.
3. Music wire is eight times stronger than normal tennis string for the same diameter.
4. A burst disc is used in the air cannon to release pressure and volume as fast as possible.
5. The air cannon can launch tennis balls at speeds of up to 560 miles per hour.
6. A custom 30-foot long brake cable is used to operate the high-speed camera from a safe distance.
7. The experiment successfully diced a tennis ball using a custom-made razor racket.
8. Two tennis balls were also successfully diced using the same razor racket.
9. Three tennis balls were attempted to be diced, but the result is not explicitly stated in the text.
10. The experiment was sponsored by Strong Hand Tools and Online Metals.
11. The air cannon was capable of launching a tennis ball at 500 miles per hour that could cut through a watermelon.
