for us old timers
don herbert, Mr wizard has passed away.
in the early 60's he had a great show that made science and experiments fun.

At least he made it farther than many.  RIP Mr. Wizard.

I just had an argument with my drummer regarding the hanging of backdrops because I seen a Mr Wizard program teaching about string tension, and knew her idea wouldn't work .  
 
Rest easy Don!  And remember your saftey goggles.
