If it ain't broke, don't fix it, as the saying goes, and this proved to be true for a very early design of the mousetrap.

In an attempt to build a nest, the mouse entered the trap and activated the see-saw mechanism. Unfortunately, the rodent did not make it. The perpetual mousetrap, on the other hand, clearly does!

Arthropods, like centipedes, typically have a waxy coating to retain moisture. Well, most arthropods aren't centipedes! Centipedes lack a waxy coating, despite the fact that they appear shiny, making them vulnerable to moisture loss. They inhabit very damp, dark areas as a result. However, their lack of a waxy layer is not entirely a drawback. They can move more quickly because the layer isn't there.

Though the duo would later receive medical insurance and yearly stipends from the company, they never saw the type of money they had hoped for.

It takes a lot of water to produce the cotton required for clothing.

People call it the God particle since Leon Lederman coined the term in his book of the same name. Marketing brilliance, but completely incorrect. (Aren't they all small particles of God?) In the opening chapter of their book, Lederman and his co-author Dick Teresi explain that "the publisher wouldn't allow us to name it the Goddamn Particle, though it may be a more appropriate title, considering its evil character and the expense it is creating."

We watch television far too much as a culture. Unless you are watching something educational or spending quality family time when everyone is too exhausted to do anything else, relaxing is typically a complete waste of time. However, there is no more wasted time if you crochet. I finished most of my projects while watching television, and each time I did so, I felt accomplished.
