You can feel the wind, can’t you? You can hold up your hand when you’re outdoors and feel it. But you can’t see it. Have you ever noticed that?
If you haven’t noticed that, then don’t feel bad. It’s just that you and I don’t have the keen scientific mind of Smidge Manly. He did notice that, and what’s more he tracked down a couple of experts who could help him, and you, the ignorant public, to understand why.
Rejoice, for the third episode of Smidge on Science is with us, and it contains an unexpected appearance from an old friend!
