Jimmy's Food Factory
Farmer Jimmy Doherty sets up his own food factory in a barn. Using farmyard and household junk, he makes breakfast with a bang when he uses a specially built cannon to create puffed rice cereal.
At a yogurt factory, there's an invisible, unpaid workforce of billions to help Jimmy make his own strawberry yogurt.
And tea is Jimmy's favourite drink - he has fifteen cups a day! So he's in heaven when he visits a tea factory to find out how the chief tea taster makes sure every cuppa tastes as good as the last.
