|Heat rising from a candle causes an aluminum coil to turn.
|Grade 1 - Motion
Small candles (possibly birthday candles)
Needle and thread
Make a "wind snake" by cutting the aluminum foil in a circular pattern (see picture).
Suspend the snakes from the ceiling on a thread so they are approximately 25 cm from the tabletop.
Light the candle and place it on the table directly below the wind snake.
|Students must be made aware of the danger involved when using candles.
|Hot air rises and as a result, the candle heats the air under the snake. The snake begins to turn as a result of the warm air rising and following the pattern of the coil.
