Everything Under The Sun

2. Why are rainbows so colourful? Why do we sleepwalk? Why do some people spit when they're talking?

In this week's show we answer three questions from Wren, Abi and Tomos. They would like to know why rainbows are so colourful, why some people talk in their sleep and why some people spit when they're talking? We discuss where the rainbow's colours come from and we talk about Iris, the goddess of the rainbow, and why the colours of our eyes are named after her. We discover the parts of a sleep cycle when you're most likely to sleep talk and finally what causes spitting, how to stop it from happening, as well as the amount of saliva our bodies make each day - it's a lot more than you might think!
