TV's 'Mr. Wizard' Don Herbert dies at 89 By LYNN ELBER, AP Television
Writer

Don Herbert, who as television's "Mr. Wizard" introduced generations
of young viewers to the joys of science, died Tuesday. He was 89.
Herbert, who had bone cancer, died at his suburban Bell Canyon home,
said his son-in-law, Tom Nikosey.


I found him on the the web about a few months ago and sent him a note,
asking about a demonstration I saw him do at a live show when I was a
kid that I still don't understand (it involved a piece of metal tube,
some window screen and a propane torch.)

Now I know why he didn't answer.

Godspeed, Mr. Wizard.


The one demonstration he did that I wish I knew how he did it was when
he poured a pitcher of a clear liquid into another clear liquid and they
both suddenly went black in the middle of the pour.
