Johnny Ball invites you to sit down and says Are You Aware of Why You Wear What You Wear?
Each week Johnny takes an entertaining excursion into an aspect of everyday life that you might be taking for granted.
This week he delves into the past, present and future of textiles. Did you know that you are wearing either animal, vegetable or mineral - that your socks could have been growing on a bush - and that some materials end up on the moon?
Meanwhile, get weaving with this - which is the odd material out: leather, cotton, wool, silk?*
