The Invisible Megaphone

All of our winning contestants today will be taking home their very own invisible megaphone. If you guessed A or C, you weren't too far off. We used to think that the first recorded sound was a recording of Mary Had a Little Lamb from 1877. But scientists found a recording from 1860 of a different song called, a la claire de la loo. And if you chose C, for the most part you actually can't hear any sounds in space.
