Watch Mr. Wizard is an American children's television series that demonstrates the science behind ordinary things.

[1] Author Marcel LaFollette says of the program, "It enjoyed consistent praise, awards, and high ratings throughout its history.

"[2] It was briefly revived in 1971, and a third version of the show ran during the 1980s on the children's cable television network Nickelodeon as Mr. Wizard's World.

[3] In the weekly half-hour live television show, Herbert played a science hobbyist and every Saturday morning a neighbor would come to visit.

The children were played by child actors; one of them (Rita McLaughlin) enjoyed a long subsequent acting career.

Mr. Wizard's World, a faster-paced version of the show, was shown three times a week on Nickelodeon, the then-rising kids cable channel.
