Kimberley and Gary's great grandad can magically transport them into the past. Grandad's magic extends to allowing he and the children, even in modern dress, to be accepted as guests of the people they visit.

Grandad Albert starts taking the children further back in time, his magic can now extend to different places, even abroad to France and Crimea.

We now meet a new Grandad and two new children, Tom and Nikki. This time Grandad's magic relies on his collection of old 16mm films - when they are projected he is able to take his grandchildren 'into' the films and back to the time when they were made. All the adventures now take place in 1901 and have a recurring cast of characters.

Another new Grandad takes over for this season. This time Magic grandad travels through time on his own, meeting with his many grand children only when he finds something "brill-a-brill" to show them.

Another new Grandad, this time he takes his many different grandchildren to meet famous people from history and lets them ask questions.

Magic Grandad now has a magic pocket watch which he uses to bring up more information on the famous person he and his grandchildren visit. The format has now changed slightly, the famous person is visited twice at different stages of their lives.
