One day a little girl was watching her mom make a roast beef. She cut off the ends, wrapped it in string, seasoned it and set it in the roasting pan.
The little girl asked her mom why she cut off the ends of the roast. Mom replied, after some thought, that it was the way that her mother had done it.
That night grandma came to dinner and the little girl and her mom went to her and asked why she had cut the end off of the roast before cooking. After some thought grandma replied, that was the way her mother had done it.
Now great grandmother was quite old and in a nursing home. But the little girl went with her mom and grandma to see her and again asked the question.
Grandma looked at them a bit annoyed and said, "So it would fit in the pan, of course."

Davy's safety lamp

In 1815, English chemist, Sir Humphry Davy of London patented the miner's safety lamp. Miners at work constantly met firedamp, an explosive mix of methane gas and air, during the working of coal. This was an almost insurmountable obstacle to the working of many of the collieries until the discovery of the safety lamp. The flame of the safety lamp is surrounded by a copper or iron gauze cylinder, with openings no more than 1/24-inch. Such a fine gauze prevents flame passing through, but fails if coarser. The wire absorbs or conducts away the heat of the flame contained inside the lamp so it does not explode gas outside the lamp. If firedamp is present, a pale blue flame appears around the central flame. This warns a miner to leave the area immediately!
