Partial Vacuum

Created Feb. 5, 2024 by Sun West School Division

Science Background:

· The covered flames go out because the trapped air is used up

· The fire warms the trapped air causing it to expand and be pushed out of the jar

· When the fire goes out the air cools which causes the trapped air to contract creating a partial vacuum in the jar

· The jar and the container are forced together allowing you to lift the whole system.

Materials: plasticine, plastic container with a smooth bottom, birthday candles, water, matches, jar
