Fab Lab is a British television programme designed for pre-school children. It was aired on the CBeebies channel from June 2002 until October 15 2006,as well as CBeebies on BBC Two.  It is an introduction to science, nature and technology for young children.
The two pixies live under the floor of a large garden shed known as the "Fab Lab". The shed is used as a laboratory by Prof who investigates various phenomena such as rainfall or the germination of plants. He explains features of the physical and natural world to the pixies, sometimes with the aid of a personal computer which Prof uses to show video sequences. Prof is very partial to green biscuits called "Pixiebicks" with which the pixies sometimes bribe Prof to expand his explanations.
At the end of the programme a whistle is heard, upon which Prof says that "Mrs Whistle" (presumably his owner) is calling, and leaves the shed.
