Ice candle

Ice candle is a kind of candle made from water. It is fantastical and looks like a lamp-shade. It has been made in cold areas in winter. It melts in a few days so we can enjoy it for a moment. 
History.
The Ice candle was first made in Shimokawa, Hokkaido. In Shimokawa, there are few days in a year when the temperature exceeds 30 degrees below freezing. So this town is known as extreme cold. The members of “Egg of Columbus”, which is a Town Development Idea Semester in Shimokawa, had thought about some ideas on how people enjoy a cold winter with snow. In 1985, they found a sentence, “...the flame moves in the ice block, it changes to the natural lamp-shade quickly, the flame in the natural and pale clear glass lights up in the garden fantastically...” This is from “Live in north literary calendar, Northern area column (Kita no kurashi saiziki, Hoppo-ken column)” written by Ryuichi Ito who was a professor of Hokkaido university of education. He wrote about the candle which is made by Scandinavian Finland children. The Egg of Columbus got some hints to create the Ice candle from that sentence. In 1986, the Ice candle was created. They put a wish for people to be able to spend winter happily in it. In 1987, the Ice candle was introduced on TV. From around that time, townspeople have made it at their own home. Now, the Ice candle is known by Japanese nationwide and loved by people living in cold areas.
How to make.
To make the Ice candle, you need a bucket, water and a cold environment to freeze water.
At night the temperature is under -16 degrees, put water into the bucket, then get it outside and through the night. Next morning, turn it upside down and take out the ice if the water has almost frozen. Flow outside the water which couldn’t freeze. Put a candle into the hole of the ice. Not to break it, treat it carefully.
We can make it with our own original ideas. For example, the colors and the shapes. If you want to color it, you can use a food coloring or paints. If you want to make it differently, you can use a milk carton or a balloon instead of a bucket.
Ice candle festival.
The Ice Candle Festival is one of the festivals which is held in winter. In this festival, the venue is illuminated by many Ice candles. The place of origin is also Shimokawa in Hokkaido. Two years later after the Ice candle appeared, the name of Shimokawa Winter Festival, which was already there, was changed to Ice Candle Festival. In this festival, the Ice candle was put not only at the venue but also at each house in the town. In total, about 7000 Ice candles were put in the town. In addition, people who go to the festival enjoy eating food outside while seeing the Ice candles. Now, the Ice Candle Festival is held in various places in Japan. Lake-Yamanakako Ice Candle Festival in Yamanashi prefecture and Mt. Nobeyama Plateau Ice Candle Festival in Nagano prefecture are also famous festivals.
