1. Dangerous glasses
3.5 Anton: Cheap sunglasses are worse than no sunglasses. They do not block ultraviolet rays, but only the visible range. In the sun, the diaphragm of the eye expands and the retina is burned out by ultraviolet light.
Expert: UV rays are really dangerous for the eyes. There are two ways to check if your glasses have a filter. First: take good glasses, where there is definitely a filter. Attach your new ones to them and start turning. At some point, the picture starts to fade. So the second glasses are also with a filter. There is an easier way: point the lenses at the monitor and start rotating. At some point, the screen will be almost invisible. And even simpler: plastic glasses will never block UV rays.
2. Oxygenated milk
Nyle: Buy a kilo of ice cream and a liter of milk. Beat all this strongly and drink in one gulp. Rapid oxygenation: fly away faster than drugs.
Expert: I don't understand how milk and oxygen are related? Well, he'll make a milkshake. In general, with oversaturation of oxygen, dizziness occurs. You can lose consciousness.

3. Essential oil in the shower
Partak Starshenbaum: If you pour a teaspoon of essential oil into a hot bath, sit in it, and then get under a cool shower, it will be very painful.
Expert: Nothing will happen.
4. Poison in circles
Berdin-Lazursky: If your plates or mugs fade from lemon or wine, then all sorts of heavy metals are leached into your food from the glaze of the dishes. This is not fatal, but it can damage your health in the long run.
Expert: Where do heavy metals come from in dishes? In any case, the strength of citric acid will not be enough to break down the coating of the cookware to such a dangerous state.
5. Heated glycerin
Berdin-Lazursky: You must not heat glycerin. At best, you cry, at worst, sit back.
Expert: It's true. Acrolein, the strongest carcinogen, is released. I'm not sure about crying - my eyes are unlikely to water. Another question: why would you heat it at home? Glycerin is most often used in household detergents.
6. Plastic and sun
Roman Mova: Do not leave plastic water bottles in the sun or in cars in summer. When heated, the plastic is destroyed and begins to fall into the water. And there everything you want, up to carcinogens.
Expert: Too small doses. That's not fatal.
7. Honey bomb
Lenard: After mixing honey, baking soda and vegetable oil in a plastic bowl, don't microwave it. The resulting napalm will swell and explode.
Expert: Ingredients have nothing to do with it. If you heat a closed bottle of water in the microwave, sooner or later it will explode. Microwaves heat the molecules of liquids.
8. Grapefruit and pills
Lolichka: Grapefruit (including juice) contains substances that slow down the liver enzymes. These same enzymes destroy some drugs. Therefore, you can catch an unexpected overdose. In the instructions for the drugs, they almost do not write about the interaction with grapefruit.
Expert: We need a doctor's consultation. But I think, if it were serious, the instructions for the drugs should indicate this. Pharmaceutical companies take these things seriously.
9. Do not close coffee to go
Vladislav: When buying coffee in cups, remove the plastic cap. Because it is made of polymers that, when in contact with hot or alcohol, release toxic substances.
Expert: This is a myth. As with plastic bottles heated in the sun.
10. Ice and salt burn
paranitrotoluol: If you hold a pinch of salt and a piece of ice in your hand, hold it - you can grab a burn.
Expert: True. This is difficult to explain in simple terms, but roughly speaking, salt enhances the effect of cold. If you want to quickly chill a bottle of water, don't just throw it on the ice, but add salt first. For the same reason, in cooking, water is salted when the water boils. When salt gets into the water, it lowers its temperature.
11. Formic acid
Atheist in a trench under fire: Formic acid destroys the retina irreversibly.
Expert: It's hard for me to imagine an everyday situation in which you have formic acid at home. It is used in forensics, in chemical analysis. But in general, if it gets into the eyes, it will obviously burn.
12. The laser beam burns out the eye
Atheist in a trench under fire: The laser glare destroys the retina.
Expert: It all depends on its power. A child's pointer with a red dot is unlikely to hurt.
13. If pipe cleaner comes into contact with your skin
Evgeniya: Be careful with pipe cleaners, they are usually quite concentrated alkali solution. Unlike acid, when it comes into contact with the skin, at first nothing is felt, but then the skin peels off
If you notice something that has got on your skin, it is better to rinse not just with water, but with a weak acid solution: diluted vinegar, lemon juice.
Expert: The alkali used in household chemicals is really dangerous. Yes, there will be a burn. But I do not advise you to waste time preparing an acid solution. Easier to rinse with tap water. Otherwise, you take longer to transport. In general, in laboratories, weak solutions of acid are at the ready, if suddenly alkali gets on the skin.
