Liquid Toy Physics

Slime is a toy with the properties of a non-Newtonian liquid.

It is usually made of borax and some polysaccharide, such as guar gum.

If the slime is not touched, it will spread on the surface. Abrupt action causes it to flatten, change shape, and even tear.

Who ever said Physics was dull?

Case in point: the centripetal force that makes a body move in a circle. This force is always directed along the radius toward the center of the circle along which the body is moving.

"Impossible" table made on the basis of the simple tension laws.

Gallium spoon and hot water.

Stirling engine

A heat mechanism with a working body consisting of gas or liquid, moving in a closed space, a type of external combustion engine.

One of the "perpetual motion machine" prototypes

Scientists are racing against the clock to find a source of perpetual energy. For sure, we'll see it in action before long.

Fascinating dandelion experiment

The reason for this is the fatty layer covering the seeds.

All seeds have a phospholipid layer that envelopes each of their cells, so they repel water.

A knowledge of physics can help you create awesome, but sometimes HATEABLE things!

In 2019, the Nobel Prize in Physics was awarded to astrophysicist Michel Mayor, who discovered a unique exoplanet

And that's how the news of the award caught up with him, in a casual coffee shop at a Spanish airport. As the photo was taken, his inboxes were clogged with messages and congratulations.

Acetylene combustion and explosion in slo-mo (330,000 frames per second).

Magnificent view!

Centripetal Spheres

That's an interesting toy, illustrating the oscillation of energy between elastic potential energy and kinetic energy of rotation.

Physics in circus

The law of conservation of angular momentum is used in circus art. When a juggler tosses up his Indian clubs/balls/plates he puts them into rotation.

☝🏻 Only in this case the objects return to his hands in their correct position.

Laser applications

In medicine, lasers are used as bloodless scalpels, such as in the removal of cataracts and lens replacement.

They are also used in teeth whitening. For this purpose, an oxygen-containing gel is applied to the tooth surface and the tooth is irradiated with a laser.

The laser light causes a chemical reaction in the gel that releases oxygen.
It penetrates deep into the tooth enamel and whitens it.

Chemical reaction through a thermal imaging camera

A thermal imaging camera is a device for observing the temperature distribution of a test surface. The temperature distribution is shown on the display as a color picture with different colors for different temperatures.

All bodies with a temperature above absolute zero emit electromagnetic thermal radiation according to Planck's law.

Dissolution of gold in mercury

The process by which gold is dissolved in mercury is the basis of a method for purifying the noble chemical element from natural impurities, and is used in the extraction of the precious component from the rock to cover the surface of products.

Low pressure air syringe

Under the influence of a strong electromagnetic field, the gas in the syringe is ionized and transformed into cold plasma

Helicopter physics

☝🏻 A helicopter, unlike an airplane, is capable of rising vertically upward.
Lift force is provided by the bearing propeller. However, the rotation of such a propeller, according to Newton's Third Law, should cause the body to rotate in the opposite direction, which would turn the machine into a real merry-go-round.

To avoid this, either a second propeller rotating in the opposite direction is placed over the first propeller, or a tail rotor is placed on the tail. In addition to maneuvering itself, it prevents the hull from spinning out, neutralizing the movement of the main rotor.
