In this episode, we will learn a little about food and eating in space. We will look at the history of the food astronauts eat, comparing what it was like to how it is today. We will also look at how they eat in space. Then we answer questions from Rowan Olsen, who wants to know why oil is slippery, Omari in Vancouver, BC, who wants to know about the Big Bang, and George in Melbourne, Australia, who asks why sand on your shoes can make playground equipment more slippery.
