Blue Peter: Slugs, Roller Coasters and Tin Foil Art

Helen and Barney have had exclusive access to follow the construction of the biggest roller-coaster in Britain and they'll be one of the first who get to ride it. It's a record breaking ride, but you'll have to watch to find out why! It's all getting a bit slimy in studio when a slug expert pops in to show Helen and Barney the spotty Leopard Slug and the flattened Pancake Slug. There's even a Banana Slug that's bright yellow - you really wouldn't want to find in your lunchbox.
