Mix sugar with sulfuric acid
(4) | 25/01/2020 | Sugar is mixed with drain cleaner containing 98% sulfuric acid. The sulfuric acid removes the water from the sugar with a strongly exothermic reaction, releasing heat, vapor and sulfur oxide.
Self-heating foods in Japan Footage of how the self-heating meals offered on flights in Japan work. Pulling a string on the box, it starts a chemical reaction that heats up your meal in a matter of seconds. This chemical reaction takes place in a small pouch under the food, and contains three chemical elements: calcium oxide, aluminum powder and sodium bicarbonate. When the small string is pulled these elements are mixed with water, causing a vigorous chemical reaction that releases heat.- What will happen if we put milk into a bottle of Coca-Cola; The effect of milk mixed with Coca-Cola 6 hours. Mixing two liquids water separates from the rest of the ingredients. This separation occurs as reaction of phosphoric acid containing the Coca-Cola with particles of milk. The molecules of phosphoric acid are appended in molecules of milk, causing an increase in density and separation from the rest of the liquid. The remaining liquid is mostly water, has lower density and stays on top of the bottle.
- Refreshment on a hot spoon TikToker from the channel @flames_vs performs an experiment by pouring a few drops of Sprite on a hot spoon. The spoon is placed over the flame of a burner. The water in the Sprite evaporates leaving only the sugar, which then turns into candy.
- Magic with a gas The heavy gas sulfur hexafluoride is 5 times heavier than air, which makes experiments with it look like magic tricks with one "invisible water".
- Cavitation in a glass water bottle Cavitation in a glass water bottle being hit by a hammer. Cavitation is a phenomenon in which the static pressure of a liquid drops below the boiling pressure of the liquid, leading to the formation of small vapor-filled cavities within the liquid. At higher pressure, these cavities collapse and can create shock waves that can damage the container. Video in slow motion at 82.000 frames per second from them "The Slow Mo Guys".
- A dog owner pretends to drown A man pretends to be drowning in a swimming pool, to see his dog's reaction. The dog will immediately run to help him by jumping into the water.
- Smarter than humans The incredible reaction of a dog, when he sees that the two young children of the family lose their ball in the water. The dog will rush to pull the little boy trying to catch the ball, and then he will take with his mouth an abstinence to recover it from the water.
- The waters of a river meet the sea People on a boat record the point where the waters of a river meet those of the sea. The difference in density due to the salt delays their mixing, and because river water contains mud, this unusual separation is clear.
- Why should not you put water on an anvil Blacksmiths often take pictures as they strike a metal at the anvil, with a spark bursting everywhere. This explosion effect is created by putting water on the anvil, heating steel to its melting point and then tapping the steel on the anvil. The blow creates a blast of steam that launches many sparks, but it is quite noisy and dangerous.
- The acid by name “Piranha” This is a concentrated sulfuric acid compound, water and hydrogen peroxide (oxygen) in a ratio of 70:30. Great care must be taken during production and hydrogen peroxide must be added to the acid very slowly, preferably during mixing. Piranha solution is often used in the microelectronics industry, BC. for the cleaning of light-resistant residues from silicon tiles. It is also used in laboratories for cleaning glass containers or pipes.
- Explosion at a copper factory (Russia) An explosion is caused in a copper furnace, at a factory in Norilsk, Russia. When a container pours cold metal into the oven, it probably also contained a quantity of water that provoked this violent reaction.
- Fire in the fryer (fail) The oil from a fryer ignites in the kitchen of a restaurant. One of the employees, who is obviously not trained to deal with such situations, will have the worst possible reaction: will pour water into the fryer. The water is immersed in the fryer and immediately evaporates to the surface, thus forcing the oil to be blown into the air and violently igniting the fire instead of extinguishing it. In such cases, the fryer or pan should be carefully covered with a damp cloth, to stop the supply of oxygen and to "drowns" the fire.
- Destroyed a bridge with a kick A security camera on the city Gu China, captures the moment a young kicking a concrete pillar on a bridge. The column falls into the water, but entrain other columns 214 to which it was linked chains. The destruction continued along 700 meters.
- Rube Goldberg machine involving a cat The user of TikTok "High School Hoops" He spent over 10 hours preparing a Rube Goldberg machine in his home, but had not provided an agent almost spoiling chain reaction. The ping pong ball that should have fallen down stairs in a container of water stopped the cat, but paradoxically left it in the right place again.
- What happens if you neglect to change oil in your car In a garage in Massachusetts United States, someone left his car for inspection saying that he had a strange smell and was not taking forward. Trying to control the oil filter, the engineer found that the car's oil had solidified and turned into a disgusting jelly. As noted later, the owner had neglected oil change for several years. An admixture with water or antifreeze - or a fault in the crankcase - probably created the problem, but which would have been avoided by a timely oil change.
