"He's the superman of science, and he loves to play with fireMy kids love Mr G. Here's a link to his 'Do Try This At Home" series...
The things he'll do, you can too, if you so desire
Do try this at home with Mr G!"
He also has "30 Seconds With Mr G" - also good value!
(but beware just searching YouTube randomly for "Mr G" - there's also an Australian singer of the same name who is not entirely family friendly... Once you follow the link, then click on the username mindpaint to see 'our' Mr G's other videos )
