The spiral pattern above, have you ever seen it dizzy?
Anyway, the explosion is already dizzy
Today’s explosion experiment
It’s about the spiral
And let it spin like crazy!
Prepare the materials together
Start today’s experiment!
-Spinning Paper Snake-
Use a marker to draw a spiral pattern on colored paper
Use scissors to cut out a “paper snake” along the spiral pattern
Stick the toothpick on the candle and insert the refill on the toothpick
Hang the cut “paper snake” on the refill
Light the candle and the spiral “paper snake” whistles around!
The candle was lit, and the spiral spun up, as if dancing lightly.
The principle used in this experiment is mainly: after the candle is lit, the temperature of the flame increases the temperature of the air above, at this time the volume of air expands, the weight is reduced, and the hot air flow rises, when the surrounding cold air quickly fills, so a circulation is formed, and when the circulating air flow through the spiral, it drives the spiral to rotate!
