Mr. Wizard (nee Don Herbert) was a science educator who made children appreciate the wonder of experimentation and the fun of blowing shit up.
He was also kind of a dick.
In the following super-cut featuring Mr. Wizard you will see that, although his experiments were super cool, he kinda thought kids were stupid shits who couldn't do anything right unless he was there supervising them.
Which he was probably right about since children are notoriously retarded.
I still miss that asshole though.
