The Preacher and the Peanuts

A preacher visits an elderly woman from his congregation. As he sits on the couch, he notices a large bowl of peanuts on the coffee table.
"Mind if I have a few?" he asks.
"No, not at all!" the woman replied.
They chat for an hour and, as the preacher stands to leave, he realizes that instead of eating just a few peanuts, he emptied most of the bowl.
"I'm terribly sorry for eating all your peanuts. I really just meant to eat a few."
"Oh, that's all right," the woman says. "Ever since I lost my teeth, all I can do is suck the chocolate off them."

Catalysis

In 1823, the effect of platinum as a catalyst was investigated by Johann Wolfgang Döbereiner, who found that hydrogen combined with air in the presence of platinum powder to form water, in a reacttion so vigorous that the filter paper holding the powder was charred. (It was later that the term catalysis was coined by Berzelius, in 1835.) Within a few days, on 3 Aug 1823, he invented the Döbereiner lighter process using the effect he had observed. He ignited a thin jet of hydrogen by passing it over spongy platinum in air. He designed a jar-type lighter using this method. Within three months, news of his discovery had been reported in some dozen European science journals. His lighter design was taken up by manufacturers to replace starting a fire with flint and tinder, and was in production for several decades.«
