The first tires were made of wood, which can be seen from ancient Chinese chariots and foreign gentlemen's carts. Later, when explorer Columbus explored the new world in 1493-1496 for the second voyage to the island of haitians in the west Indies, he was taken aback by the fact that the local kid was playing with a hard piece of rubber. Later, he brought this wonderful thing back to his homeland. After several years, rubber was widely used, and the wheels were gradually made from wood to hard rubber. But the rubber tires were solid, and they were uncomfortable and noisy. It was not until 1845 that the Scottish civil engineer, r.w. Tom, made the inflatable tyres and got the British government's patent for "the wheels of carriages and other cars". The first inflatable tire was born on December 10 of that year. The first man to buy a pneumatic tyre called a list, a nobleman, and the price of four tires weighed forty-four pounds and two shillings. In 1847, scientific American magazine introduced Tom's inflatable tire, calling it an epoch-making improvement. The British, however, too much attention to the traditional gentleman, in order to protect the carriage, limiting the development of the steam car, the speed of cars in urban areas are limited to 2 mile per hour (3.2 km), suburbs of 4 mile (6.4 km). In this way, Tom's invention had no market, so it was gradually forgotten. That is to say, Tom's first tyre revolution did not bring the sun the same light as the sun, for the darkness that human beings should endure seems to have not come to an end. But the sun is always out, because of the human and all things need it, more than 40 years later, in 1888, England people in Ireland when veterinary j. b. Mr Dunlop taken out a patent on the pneumatic tyre. At that time, Mr. J. b. Dunlop 10-year-old son Johnny bought a tricycle, but because the tires are made of hard rubber solid tyres, therefore, walking on the road is full of stone is very uncomfortable, son's complain inspired Mr Dunlop, therefore, been forgotten more than forty years of pneumatic tyre came out again. Along with the progress of The Times, invented by Mr Dunlop pneumatic tyre soon have been applied on the bike, and quickly to the automobile industry, for the world made great contributions to the development of automobile industry

Before Christmas fairy lights were even invented, a lot of people all over the world were using candles as a way to celebrate and help spread the Christmas cheer. These candles made a festive glow that people of any age could enjoy and respect. There were no battery fairy lights previously, so people needed to use what they had saved to help you show their holiday joy. Candles were even used as ornaments on trees in those days, which is an evident fire hazard. This became especially hazardous for the surrounding people if the Christmas trees would will dry up. This made the trees considerably more flammable and designed a a large amount of danger whenever fire was nearby. Nowadays, we do not have to worry about flammable candle decorations because we have LED battery lights as well as other rope lights available that will not pose any serious threat to transforming into a fire hazard. In the early days of Christmas lighting, just the wealthy meet the expense of candles, so it was something only created by the affluent and celebrities. We now reside in a time where almost anyone can readily celebrate the holiday season by incorporating readily available Christmas decorations.
