A set of experiments in physics "Wonderful Lamp" will immerse the child into the fascinating world of scientific research. A young scientist will conduct an experiment that will help him to better understand physical laws and watch how warm and cold air moves!

how to make experience
  • bend the top of the lamp around the perimeter of the circle along all lines of the bend inward, and the valves - upstairs, like shown in the figure in the instructions.
  • Fold the top with a button.
  • Attach a bilate adhesive tape to the bent part along the entire length of the circle.
  • Take a sheet with the image of the carousel and glue Its to the top of the lamp-this is how you get the main case.
  • Assemble the main supporter, as shown in the figure in the instructions.
  • Put the base of the case on the holder and put the candle on the basis of the holder. < /Li>
  • Burn the candle.
  • You will notice how the housing will begin rotation.
  • Only with adults

    a candle is used in the course of experience - this is work with open fire! The experiment must be carried out under the supervision of adults.

    how it works

    This causes the formation of a convection flow of air, which goes up along the carousel case. The valves at the top of the case are located at an angle, and when the air flow collides with them, they are displaced in one direction. According to the law of preservation of the impulse, this displacement causes an equal and opposite displacement on the case of the carousel. As a result, the case begins to rotate in a direction opposite to the direction of the valve displacement.
