This cat has become a real salvation for little chickens. Their mother hen died and they were left alone. The cat began to climb into their box and sleep with them, warming them with its warmth.

It's science fiction🧲

But it's a magnetic field that can create different geometric shapes from metal particles.

New 3D printer can print record long objects

The United States unveiled a new printer that can print very long objects. The device can work up to 200 hours without human supervision.

The CR-30 uses a print head tilted at a 45-degree angle, so when the heated belt moves, the models are printed from the front and back simultaneously.

The way soap acts?

Liquid molecules experience mutual attraction forces, thus causing surface tension.

By getting into the surface layer of water, soap molecules noticeably weaken the surface tension forces.
Soap and laundry detergents reduce the surface tension of water, increasing its permeability. Therefore, soapy water soaks in and cleans fabrics and other materials, taking the dirt away with it.
