Happy holidays! Two differently colored flames rotate on a turntable with a tubular screen attached to it. The hot air from the flame rises up the tube, drawing fresh air that comes in from the sides to replace it. As air moves into the tube, the rotating screen deflects it slightly off-axis. As the air gets closer to the flame, conservation of angular momentum causes it to spin faster, forming a vortex characteristic of a tornado.

Whatever force makes the flames behave countwrintuitively this demonstrates a mind gobbling law of thenature

Here's the thing I want to know. why is the flame going with the air current? If the table is spinning counter clockwise then shouldn't the wind from that rotation make the spiral go clockwise instead?

It may be similar to how helium balloons go to the opposite side of a turning car - fire is lighter than air so it may be pushed to the other direction. But I don't know really

Huh, red looks like it’s always behind green, is there a reason for this?

@lazyladyforever 3 жыл бұрын

green light has scientific stuff that lets it pass through red light I'm not a scientist but this might be close

Basically, green is brighter

Our eyes are more sensitive to green light. For example, a green laser looks much brighter than a red one with the same wattage.

What gives them colors?

@DanielRosenberg 3 жыл бұрын

The fuel is methanol, and the colors come from boric acid (green) and lithium chloride (red). I dissolved about ten grams of each in 100 ml of methanol to make the fuels for the flame tornadoes.

It was good for the first 10 seconds. At least you could reverese the direction of the rotation.

can you possibly spin so fast, it will become one color?

@ronniepirtlejr2606 3 жыл бұрын

I was thinking the faster you go the more Helix you will have. To twist, three twist, eventually looking like a spring?
