Self-heating foods in Japan
(5) | 13/09/2024 | 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.
Ready meal with automatic heating, from Japan This video shows us a kind of standardized food from Japan, from a product line called "food rescue". The kit contains not only burgers and rice, but also two materials that cause exothermic reaction and heat the food (consist mainly of aluminum and water). So, You can eat your food hot without the need of electricity or gas. It costs about 6,70€.- Mix sugar with sulfuric acid 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.
- Surprise for his birthday The reaction of a 3 year old boy in Japan when he discovers his gift, a box containing his equipment superhero Kamen Rider Zero-One. His dad puts the game silently behind his back, in order to make a surprise for his birthday.
- A large piece of sodium in water The sodium metal reacts violently when in contact with water, producing hydrogen. Like all other metals, sodium reacts exothermically with water, as a result the heat released is often sufficient to cause a small explosion.
- The effect of low temperature on tin At low temperatures (at about -30°C), tin begins to dissolve in an autocatalytic reaction called and "tin leprosy". Already at 13°C pure tin turns into powder, something that is hindered in its industrial applications by the addition of antimony and bismuth. Here we see a timelapse of this tin wear, which took place over a period of about two hours and temperatures around -40°C.
- The balloon game Balloons inside each other are filled with water and then hung from a string. Each player must stand under the balloons and avoid getting wet by carefully cutting each balloon with a knife.
- The hydrophobic properties of cocoa Cocoa powder is a hydrophobic substance, which means that water cannot enter it when it is in a large amount. When mixed, it can apparently be mixed in liquids, but when stationary the liquids flow over the powder as with any other hydrophobic substance.
- 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.
- Pills on the stove The strange reaction of some calcium gluconate pills, which I placed on the hot eye of a kitchen.
- Dive into the water In Osaka, Japan, a young man tries to take a big dive from a bridge into the river. Unfortunately, the project will not have the end it expected.
- Jetson ONE flies in a forest A new demonstration of the Jetson ONE electric aerial vehicle, produced by the Swedish company Jetson, this time flying through a forest. The Jetson ONE which is sold as a kit at the price of 79.000 Euro, has an aluminum structure and is based on 8 engines and 8 propellers. To pilot it, its operator uses a throttle and a 3-axis joystick. The flight controller limits the maximum speed to 102 km / h.
- The waterproof water Dry water is a substance that looks like a fine white powder and is created from water droplets coated with silicon vapor.. It is so named because it consists of 95% water but does not wet the surfaces it comes in contact with. Can be produced by stirring silicon vapor nanoparticles with water.
- Arched gates protect Osaka, Japan from floods Osaka is also called "city of water" as it is located between the sea and the river Yodo. Huge movable arched gates at the points where the river narrows, protect the city for many years from the tides caused by large hurricanes.
- 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.
