Circumcision edge of the plastic bottle is not always convenient and, moreover, is not always nice and smooth
1. I took a plastic bottle of mineral water (1 L).
2. Cut part of the bottle.
3. Place the top sheet of paper and held a hot iron (paper needed to plastic is not stuck to the sole plate).
4. The sharp edges of the bottle from the heat rounded. Caution – iron hold briefly and always check that there is a piece of paper.
On a bottle of mineral water works fine. A small bottle of yogurt (0.33 L) resisted. One can see the plastic tightly. In general, a number of small bottles is not passed angry.
