Fun Science

The aurora borealis (northern lights) is a phenomenon of glow of the upper layers within the Earth's atmosphere, caused by the movement of charged particles of the solar wind in the magnetic field of the planet. Excited oxygen atoms cause red and green glow. Purple and invisible to the eye infrared radiation is caused by ionized nitrogen molecules. Hydrogen atoms can be the source of a weak red glow.

Magic? No, physics! The Leidenfrost Effect ☝🏻 That’s a physical phenomenon in which a liquid closer to the surface, hotter than the boiling point of the liquid, creates an insulating vapor layer that prevents the liquid from boiling rapidly. Due to this "repulsive force," the droplet floats above the surface rather than making physical contact with the hot surface.

The Elephant Toothpaste Experiment in Motion Potassium iodide (a colorless crystalline salt) reacted so violently with hydrogen peroxide that it literally pushed the products of the chemical reaction out of the flask.

Magnetic levitation of aluminum, copper and magnesium💡 Magnetic levitation is a technology, a method of lifting an object using a magnetic field alone. Magnetic pressure is used to compensate the acceleration of free fall or any other accelerations

The way a black hole twists space👆🏻 A black hole is a region within cosmos with so much gravity that it absorbs everything around it, including light. However, the word combination "black hole" itself is just a cleverly invented designation. And it only caught on due to the fact that it's convenient. A hole — because once something gets there, it cannot get back out. And the black one is that the object itself does not emit anything or practically nothing.

💦Acoustic levitation California startup Simplistyk has invented a device to levitate water. The device is called "Levizen". It applies the principle of acoustic levitation: high-frequency sound waves indistinguishable by the ear make a drop of water literally hang in the air.

🐍"The Pharaoh's Serpent" The euphonious name hides a collective image of multiple chemical reactions in the process of which there is a multiple increase in the volume of the used reagents. During the reaction, the resulting substance increases, and it (the substance) wriggles like a snake. What a fascinating sight!

Murmuration (from Latin murmuratio "muttering, buzzing") This is how ornithologists call the association of birds (commonly starlings) in huge flocks, continuously changing their shapes into a variety of figures. An impressive natural phenomenon!

Fluorescein When exposed to ultraviolet light, the green dye fluorescein emits light in the visible range, a phenomenon called fluorescence.
