Quicksand is a highly dangerous phenomenon.

You can get caught in them quite unexpectedly. All over the world there are beaches that turn into a risk zone at high tide. In the summer you want to take a walk on the yellow sand, and it suddenly begins to fall through and grab your feet.

And you have no way to get out. Panic sets in!

High-speed video of oyster mushroom and shiitake spore distribution

Scientists have discovered that the mushrooms create their own airflow to carry the spores by releasing water vapor. This causes the air to cool, creating a convective movement.

Simple unipolar motor.

5 kW induction heater

Induction heating is the process of heating an electrically conductive object (usually metal) by electromagnetic induction, due to the heat released in the object by eddy currents.

Micro turbojet engine in the garage.

Laser engraving

If the laser is powerful enough, it can engrave various forms of materials quickly and efficiently.

Why does this happen?

The wind blows and hits the surface of the dam, but the shape of the dam is curved, so the wind goes straight up, as if changing its direction across the surface of the dam.

As a result, a huge amount of wind is ejected at the very top end of the dam.

The coolest way to wash a bottle

Burning gas inside creates negative pressure, causing the liquid to be drawn into the jar. The number of gas molecules changes as the temperature of the gas decreases.
