In spring, summer and autumn nature blooms with bright colors. And all living things around the amazing variety of colors and shades. But sometimes we see in bouquets unusual plants - their color is not the same as we used to see. What's the matter? Most likely, in the artificial coloring using capillary method.
What is capillary action? Physicists explain it as liquid movement in a thin tube under the influence of surface tension forces. Capillary phenomena we observe in nature, as well as in everyday life.
PWhen wiping wet hand towel water out of thin fibers that make up the fabric, the same thing happens with paper napkins.
Moisture can penetrate even into the walls of the capillaries of the building in the building materials, so you need to insulate the walls from moisture. Plants receive water and nutrients from the soil by capillary plant system. The flowers had not been dried in our absence, to make them special "bridging" the water supply.
Let us conduct the following experiment: prepare a transparent jars or tall glasses with water and food coloring in different colors. Another need is pale, almost white, flowers, such as lilies and carnations. Dilute with water, dye, flowers put in the container. We are waiting... about a day - an amazing result!
Obey the laws of physics are not only flowers, but also vegetables. Take the Chinese cabbage for experiment - a miracle to wait a short time, a day leaves will absorb the paint and become unrecognizable beautiful. Do not object to a new way of parsley and celery, who are tired of their green color. Look, now they look like flowers.
Obtained from a variety of plants can create beautiful bouquets that are so decorative, that do not require wrapping. But look at the last photo - How to get the flower petals of different color?
Craftsmen know the answer to this question. Do roses have split the stems with a sharp knife, each part of the stem was placed in vessels with different dyes. And paint up the capillaries only to the petals, which receives water from the container. Instead of glass containers can use plastic bags for freezing foods.
You want to get a quicker effect? To experience needed paper towels or white cotton fabric, folded in the form of strips. We label paper or textile strips into cups with a colored solution. Directly in front of the liquid will begin to rise and will stain. Even more interesting to omit the two ends of dry blanks in different colors, make of them the chain. Dyes will rise by fibers and meet, creating a wonderful rainbow patterns.
Like the experiment? Next time, we'll show you how, by applying the laws of physics, to make beautiful paper flowers.
Also be sure to ask about what unusual experiments will lead your children to a complete delight!
