Greg Behrendt: Halloween Rules

I have two rules when you come to my house on Halloween. Wear a costume -- cause if youve manned your door at your own house, you know how many kids will roll up, 14 years old with no costume and an attitude. My other rule: dont grab. Let me assess you and then design a candy situation for you.

Thomas L. Willson

Died 20 Dec 1915 at age 55 (born 14 Mar 1860).Thomas Leopold Willson was a Canadian-American chemist and inventor who discovered a commercial production method for calcium carbide using an electric arc furnace. In 1893, he started a company with John Motley Morehead III in Spray, North Carolina, to try his ideas to obtain aluminium metal from its oxide. On 2 May 1892, he was using an electric arc furnace with coal tar and burnt chalk (lime). An unexpected dark, solid mass was formed. On cooling with water, a gas was given off. This burned with a bright yellow, smoky flame. Analysis showed these were calcium carbide and acetylene. Unlike the earlier method of Wöhler that made calcium carbide in an amorphous form, Willson had a hard, aggregated chrystalline form. He obtained (and defended) patents on his process. He assigned them to the Electro Gas Co. (which became Union Carbide Corp.) His other inventions included gas navigational buoys and electric arc lighting. He established calcium carbide manufacturing in Canada.«
