Read the text about hobbies.

Рис. 1. Stamp collecting

Hobby is an entertaining activity that has nothing to do with a person's job or studies. There are some types of hobbies that everyone knows, like collecting postcards or stamps, drawing or cooking. However, there are some unusual hobbies that can surprise you.

Building houses of cards as a hobby can seem a bit childish. However, a lot of people love it. It takes a lot of patience. People build not only small triangle houses, but huge multi-storey buildings too. Of course you have to be very careful — one foozle and the masterpiece is destroyed.

Painting on water is an art technique developed in Japan. You splash the paint onto the surface of water and make beautiful patterns of lines and spots. After that you can transfer your painting onto a solid surface like wood, ceramics or fabric.

Cartridges have gone out of use, but if you have some old cassettes or VHS at home, you can try to make a picture of it. The tape is elastic and can be easily arranged in any way. Also this kind of hobby gives you a chance to be environmentally friendly as old cartridges are not thrown away but given a second life.

Everyone knows woodcarving, but would you try vegetable carving? Potatoes, turnips and carrots are hard enough to become a beautiful carved piece of art. It's a pity, though, that you can't keep them for long.

Write true, false, doesn’t say:

1. Hobby is an entertaining activity that has nothing to do with a person's job or studies.
....

2. Painting on water is an art technique developed in Japan.
....

3. The writer doesn't like woodcarving.
