Some newly married friends were visiting us when the topic of children came up. The bride said she wanted three children, while the young husband said two would be enough for him.
They discussed this discrepancy for a few minutes until the husband thought he`d put an end to things by saying boldly, "After our second child, I'll just have a vasectomy."
Without a moments hesitation, the bride retorted, "Well, I hope you'll love the third one as if it's your own."
Leaded gasolineIn 1921, tetraethyl lead was first given a laboratory test as an anti-knock additive to gasoline fuel. The knock in the one-cylinder laboratory engine was utterly silenced. Even at a strength of only 2-3g grams per gallon (1000 to 1 dilution), it had a remarkable ability to quiet the relentless knocking. This invention of Thomas Midgley, Jr., of the General Motors Research Laboratories, located in Dayton, Ohio, was first put on public sale as ethyl gasoline in the same city on 2 Feb 1923. This invention of leaded gasoline came after seven years of testing at least 33,000 compounds. Previously, on hard acceleration, an engine sometimes made knocking, popping or crackling sounds, which sapped power and could damage the engine. |
