Unfortunately this article doesn't mention his books Mr Wizard's Supermarket Science, which I had as a kid and it was pretty awesome: http://www.amazon.com/Mr-Wizards-Supermarket-Science-Herbert...

He also authored a few more books:

Mr Wizards 400 Experiments in Science http://www.amazon.com/Mr-Wizards-400-Experiments-Science/dp/...

and http://www.amazon.com/Mr-Wizards-Experiments-Young-Scientist...
