For this science experiment we need :
- A candle
- Matches
- Water
-Food coloring
- a dish
- A jar

We first put the candle in the dish and ligth it
Then in a small bowl with Water we add Food coloring.
We put this mix in the dish with the candle
Then we cover the candle with the jar and wait until the flame ends
And then we see the result , the Water goes inside the jar
Why this happen¿
Because when when we cover the flame with the jar the candle heats the air inside the jar and expands it. And when the oxygen inside the jar ends, the candle goes out and the air cools.
The volume of the air decreases and the Water ríes.
