It is required to you
- Two two-liter empty plastic bottles, water, pricker, additional resources: food coloring, means for washing of ware, gloss, confetti.
Instruction
1. Take couple of plastic two-liter bottles. Naturally, empty. Remove labels. To eliminate the label, fill a bottle with warm water and leave for some time in soap water. Then uncover with bottles and carefully wash up. In the center of each cover make openings with a diameter of 1 cm. For this purpose use a pricker.
2. Now place both covers on their faces and close openings by means of the thin silicon roller. Wait until consolidation dries, and wrap up in an insulating tape around outer side of a cover. Densely connect covers with each other.
3. Carefully close one of bottles. On three quarters fill another with water. Then add gloss and means for washing of ware, or food coloring and confetti. Presence of these materials will make a whirlwind more accurate and noticeable. Make sure that did not add too many excipients. Otherwise it will be difficult to consider a tornado.
4. Turn an empty bottle, and close a cover free on the edge the bottle filled with water. Having fastened bottles with an insulating tape on the one hand, try to support the lower part by a hand with another.

6. You can experiment with a big or smaller amount of water and also using various liquids and materials added to water. Try to make circular motions quicker and more slowly. Pay attention to effect.
