Wow, it was fantastic to see so many participants in the sound quiz - thanks a lot for taking part! There were lots of great guesses - with popular answers being bike wheels, shavers, various types of engines and tools - but it's time to reveal what it really was.
The mystery sound is made by a toy called Hurricane Balls! Check out the video below for an example of what Hurricane Balls are and how they work:
• The winner in the random draw from all entries is… Marcus Manderson!
• The winner in the random draw from all the correct answers in the sound quiz is…. Alex Cox!
Congratulations to both winners, and a big thanks to all of you for taking part, and to BOOM Library for sponsoring the prizes.
