We were surprised to discover that there is no sound in the vacuum of space and amazed at how well our string telephones worked.

We explored the extraordinary workings of our ears and investigated how we could use popcorn 🍿 to help us ‘see’ sound by watching it bounce off a beaten drum or dance to Aretha Franklin on a speaker. 🔊
