Let's find out about wool with Kit and Pup! Pup is using a ball of wool to knit a hat for Kit, but he can't seem to knit the correct size. Then he gets carried away and knits a pile of woollen clothes that are a lot more than Kit needs! Through their adventures Kit and Pup find out that most wool comes from sheep, wool can be colourful and wool can be knitted into things. In the live action investigation two little scientists discover how to use wool to weave a picture, and in the material world a little explorer peeks out from inside a ball of wool.
