6 of unusual materials, with which you can work wonders. Magic exists!
Few of us can say that his favorite subjects in school were physics or chemistry. Complex tasks, incomprehensible equations, dry theory, old textbooks, boring lab, where more than writing, than to conduct experiments - it seems all this only contributed to the fact that you're not in a hurry to these lessons. But these things can not just be interesting and even exciting!
I assure you that you have changed their attitude to science after seeing. Now, if it is shown to us in school! Then, these items would be my favorite ... It turns out that in the world there are several substances that lead to a screeching halt and even scientists question the laws of physics. It seems to be the result of some magic or witchcraft. You could not even think!
1. The metal, which melts in your hands. B>
Do you think the metal melting in your hands, like ice cream - something out of science fiction? And here and there, it does exist. This metal - gallium. It melts at room temperature and is not suitable for practical use. If you place it into the hot liquid of any item from gallium, it will dissolve before your eyes. Unbelievable but true!
2. Gas capable of retaining solid objects. B>
Everyone knows that sulfur hexafluoride is heavier than air. Therefore, it settles on the bottom of any container with air. You can spend a wonderful experiment. Place the foil boat into a container filled with this gas, - and you will see a miracle. Boat will be held in the air as if soaring in the clouds. Do you want to scare your friends? Breathe a little geskaftorida sulfur - and your voice will change before our eyes. Now it sounds like an ominous baritone of the underworld. So you can be nice to play someone!
3. Coatings that are afraid of the water. B>
Imagine how you show your friends a wonderful trick. Placed as if nothing had happened finger in a glass of water, take out, and he ... dry! All surprised, as you tell a secret: it was enough just to handle these special hydrophobic coating finger. And, when the finger is located in the glass around it will form a bubble - so water will try to "run away" from you. In fact, many designers are thinking about that in the future use of such materials in the creation of waterproof clothing. I want to see this!
4. Spontaneously exploding powder. B>
Such a powder as nitrogen triiodide, at first glance looks like a pile of dirt. But we must be extremely cautious: this stuff blows up, even with a light touch of the pen! Do not worry, this material is only used for the experiments: it is dangerous even to move from place to place. In the explosion, by the way, produced a beautiful purple smoke. Effectively, anyway!
5. Hot ice. B>
Hot ice, also known as sodium acetate, - a liquid hardening under any impact. The slightest touch the liquid turns into a solid crystal just in seconds. This surface formed beautiful patterns like these, which draws a frost on the windows. By the way, this crystal is only superficially similar to the ice. In fact, this stuff is very warm, and slowly cooled. In any case, I'm starting to believe in magic ...
6. The metal has a memory. B>
An alloy of nickel and titanium (nitinol) has a tremendous ability to - to remember its original shape and return to it after deformation. It's enough just a little heat. You can drop a metal hot water - and it will return to its original appearance, no matter how much has been distorted. Scientists believe that this magical alloy can be safely used in the production. Just think: if you suddenly accidentally bent glasses, made of nitinol, it will be enough just a couple of drops of water to restore their original shape. The properties of this alloy still impressive!
And here is the video where you learn a lot of interesting things:
Yeah, in nature there is so much amazing, what you would not even know. Upon learning of the existence of these substances, you completely forget that physics and chemistry - it's very boring and uninteresting. Why only in the school do not talk about it? Then have all the students ran headlong into lessons.
Share these amazing discoveries with their friends - they would in the wild delight from seen. Especially do not forget to show this to the children believe they tomorrow are written in a circle young physicist!
