Inventions that changed Christmas

Garlands of lights
In 1880 Thomas Edison used just the improved light bulb, hung the first garland of lights around his laboratory in Menlo Park. But to mass produce the lights with various colored lights then it was another 30 years. For a long time the bulbs were expensive a luxury to use them for decorating homes.
Early Christmas trees were lit with candles, so most people burn it only for a day or two before the holiday. In a lot of Christmas lights instead of incandescent lamps use LEDs, which use less energy and last much longer.



Batteries
The existence of small regular batteries give you the possibility of electronic toys. The first, who used it, were Japanese producers who needed new markets after the devastation of world war II. The batteries used in toys before, but the Japanese began to use electricity not only for lighting and sound: they made robots that could move.



Tinsel
In the XVII century, tinsel was made of real silver, smelted it as thin as hair, wires. It was not the artificial tinsel, which is used today. Unfortunately, the silver quickly become dirty and was obviously expensive material. So the manufacturers switched to lead, which, as became known later, was poisonous and eventually it was banned for widespread use in the early 1960-ies.
