Despite the fact that chemical reactions with an unusual effect as a result, are now available even to schoolchildren, some of their results are still surprising not only in children, but also in adults. For example, luminous liquids, which are formed due to the release of energy from certain substances in water, remain popular and attract attention. They are frequent "guests" of various tricks. Is it possible to create this miracle on your own and why apply it?
How to make glowing liquid from improvised means?
Before going directly to the recipes and the magic mass creation algorithm, it should be noted that the main part of the ingredients is not so easy to get. If a certain substance acquires fluorescent properties, a chemical reaction begins in it, most often occurring in an acidic medium, with the release of energy. Accordingly, it can not be something accessible to everyone.
Mainly for this purpose they use luminol, siloxene, lucigenin - the brightest representatives of the group of chemiluminescent substances. Activators or additional components - dry alkali and copper sulfate solution. But the mass obtained after their connection is not particularly attractive, therefore special luminous paints or even brilliant green are added to it. All components are available to consumers in stores of chemical reagents.
- The main ingredient of all recipes of this type is luminol. A white or pale yellow powder chemically reacted with an acidic and neutral medium. It is he who produces the blue glow. It is noteworthy that they use it to detect traces of blood at the crime scene, because it reacts to iron. With his help, you can detect the presence of cyanide. This substance does not dissolve in water.
- The easiest way to create such a liquid involves mixing 1 g of luminol, 245 g of dry alkali or potassium hydroxide and 190 ml of Dimexidum in maximum concentration. The components need to be shaken, after which the reaction will begin, generating a blue glow. If you need another color, throw a little fluorescent dye into the container. Moreover, keep in mind that the brightness of the glow depends on the contact with the air - the stronger it is, the richer the glow will be.
- An alternative recipe involves a greater number of components: in 100 ml of water at room temperature, you need to pour 3 g of copper sulfate and pour 80 ml of hydrogen peroxide at a concentration of 3%. Then 10 ml of caustic soda solution is injected, which will become the catalyst. The hue of the glow is also regulated by the addition of fluorescent dyes, since by default the liquid will be blue. Enhancing the effect is achieved by active alkalization of the liquid.
For the last recipe, you can use not only copper sulphate, but also ferric chloride, red blood salt. Or they are replaced by blood from chicken ham, which is taken in the same volume and diluted in water. The resulting liquid is added to luminol and water in the amount of 1 tbsp.
- Even more simple composition - a weak solution of 20 ml of cold running water and 1/4 tsp. washing powder, 10 ml of hydrogen peroxide at a concentration of 3%, 5 ml of luminol solution. The latter are introduced grated crystals of potassium permanganate - just a pinch is required. The glow is caused by chlorine present in the water, so it does not need to be defended. When the ingredients are mixed, the liquid will not only light up, but also begin to spark.
Conducting such experiments, keep in mind that the mixing tank should be glass - plastic or metal will not work, no matter what quality they may be. As an alternative, porcelain can be used. And the components must be connected clearly in the specified order for the chemical reaction to proceed correctly. And it is desirable not to allow children and animals to the place of the procedure at this moment.
Practical application of fluorescent light
The obtained liquid can be processed absolutely any object, regardless of whether it absorbs it. However, surfaces that do not dry out completely will retain shine longer, while fabrics will quickly lose this effect. The same applies to the skin: it is impossible to make fluorescent patterns on the body with liquid - for this, it is better to take special paints. So where better to use the prepared mixture?
- An interesting and unusual element of the interior: a beautiful glass container with luminous liquid will replace any lamps and candles if you want to create an intimate or mysterious atmosphere.
- At any children's party, “light swords” in the form of glass cylinders filled with prepared liquid, or even glowing balls, will be popular. By and large, this mass can be poured into any hollow object with transparent walls.
It should be noted that if you plan to capture the moment of radiance of a liquid or an object treated with it, it is necessary to increase the concentration of alkali, otherwise the camera will not capture light. Basically, it removes the first seconds, that is, the moment of ignition, and in a dark room. In the photo, the maximum radiance is obtained to keep at the moment of connection of luminol and hydrogen peroxide, or at high exposure.
