This fluorescent agent can be used as a tracker that can be used for everything from detecting in living organisms to tracking rivers. Even NASA uses it to search for spacecraft that have crashed into sea.
Aulek is neither liquid nor solid, and if pressure is applied to it, such as by squeezing or patting, it will thicken and become harder.
Put Oblec on speaker, and with vibration of speaker, Oblec will be able to dance and "transform" in front of you. If you want something exciting, you can paint Oblec some color. The effect will be even more amazing!
4 instant freezing water!
A game version of Frozen? Don't worry, it's not magic! When water condenses into ice, temperature must be lowered to freezing point, but sometimes even when freezing point is reached, water may not freeze immediately, and water at this stage is called "supercooled water"(supercooled water). As long as quality of supercooled water is pure enough, place an ice cube on it at this time, and supercooled water can immediately condense into ice.
5 tablespoons, melted.
This spoon is actually made from gallium (gallium), a metal that melts at about 29 degrees Celsius. So don't worry, this glass is actually plain water.
6. hot ice phenomenon.
Just like supercooled water, sodium acetate can freeze instantly. When sodium acetate solution is in state of a supersaturated solution, and then touches seed crystal, it can cause supersaturated sodium acetate to become unstable, and supersaturated acetic acid will be a hot ice phenomenon of rapid crystallization of sodium solution.
Stealth Ball 7
This kind of invisible beads is also called superabsorbent polysaccharide. When it is in water, its refraction is very close to that of water, so its existence is almost invisible to naked eye. it is scooped out of water.
8 Milk art.
Do you want to be an artist? The "painting" method is very simple. First, put some pigments on milk, and then put some soapy water on it. When soapy water drops on milk, it will dissolve and spread, and pigments on it will flow, thus forming an artistic picture.
9 immortals descended to earth?
When you put dry ice in water, it releases a lot of gas, but before adding dry ice, add some dish soap to water and you can create this magical effect.
10 Free fall has slowed down.
Don't worry, men in movie don't practice witchcraft. In fact, falling object is made of metal. When it passes through same metal pipe, magnetic force generated slows down falling speed, but due to strong gravity, object will eventually fall.
