RGB Triad

That's how the three primary colors can be used to create a multicolor image.

Under the force of gravity, the raisin descends to the bottom. Then gas bubbles form on the rough surface of the raisin.

When there are enough bubbles, the expulsive force (Archimedes' principle) will cause the raisin to rise to the surface of the carbonated water. At the surface, the gas bubbles burst, and gravity causes the raisin to sink back down again.

Newton Disc

Allows to obtain white color from several rays of various colors.
The disk is divided into sectors of colors of the visible spectrum. When rotating it at high speed, you can observe how these colors merge to form a white tone.

Flash paper (nitrocellulose)

It has a characteristic combustion: no hint of smoldering, the jet of flame hits not only upwards, but also in all directions, indicating that in the "hearth of combustion" material burns without the participation of air oxygen. Finally, the fact that not only smoke, but also ash is not produced.

Using an acrylic prism and a gas pedal, we "catch" the electrons.

They easily penetrate deep into the acrylic and are quickly slowed down by colliding with the plastic molecules.
