Burning Candle in Water Experiment

All you need to try this super cool science experiment are a few simple materials you probably already have on hand:

  • plate with raised rim ro bowl
  • water
  • candle
  • ligther or matches
  • mason jar or glass
  • food coloring (we used blue to see it better)
  • playdough (optional for holding the candle in place)

The Burning Candle Experiment

Start out by putting the candle on plate or bowl with a lip. I suggest using a chunky tall candle so the water won’t overwhelm the candle and it has some stability. If you use a tall tapered candle, you may want some playdough to hold it in place.

Mason Jar Experiments

The amount of water used will really depend on the height of your candle and the lip on your bowl. But I’d say 1/2 cupr or so was right for us. We mixed our water with food coloring first and then poured it on the bottom of the dish.

I suggest filling out the pdf science worksheets at this point to help students make educated guesses or hypothesis!

Burning Candle Rising Water Experiment

Please do a trial before you light it to make sure your candle will fit under the mason jar or glass. Light the candle and put a mason jar over the top of the candle.

WARNING: Fire is dangerous and this should only be done under the carefuly observation of a responsible adult. Please use common sense when completing this science activity.

The Burning Candle Experiment

Have students watch carefully. The candle will start lit, but won’t stay that way for long!

CAUTION: The glass will become hot to the touch. Please wait for it to cool down completely before touching; it should be handled by an adult with care.

Air Pressure for Kids

You will observe the candle going out, some bubbles forming around the bottom of the mason jar, and then the jar will begin filling up with water.

Why does the water rise in the candle experiment

The candle went out  in the jar because it ran out of oxygen. Fire needs oxygen to live. When the oxygen ran out in the upside down mason jar the candle went out without us blowing on it. But something else happened when the candle was burning, the flame heated up the air inside the glass. The hot air expanded quickly and created higher air pressure inside the glass than outside the glass. To restore equilibrium, some of the high-pressure air inside escaped from under the glass. You may have seen tiny bubbles escaping from underneath the glass. When the flame extinguished, the air inside the glass began to cool down. Cooling air contracted, which in turn lowered the air pressure inside the glass.

Air Pressure for Kids

The remainder of the blue water was sucked in to the mason jar.

Why does water rise in burning candle experiment

Just as before when air rushed out from the glass to balance the air pressure between the inside and outside of the glass, now air wants to get in. As a result, the high-pressure air outside the glass pushes on the water, forcing the water into the glass. Visually, we can see the water level rising until the air pressure inside the glass is the same as the air pressure outside the glass.

Students filled out the remaineder of the burgning cande in water experiment printable showing the results. After you explain what happened, ahve children write their conclusion.

Extensions Ideas:

  • Try using hot water or cold water instead of room temperature water; did it make a difference?
  • Use more or less water? Does that make a difference?
  • Use a larger candle or smaller candle; does the size of the candle matter?
  • What if you use multiple candles? Multiple candles would make the jar hotter and use up the oxygen quicker; did that make a difference?
  • Use milk or vinegar instead of water. Does the type of liquid change the outcome?
  • Will using a bottle with a more narrow neck change the results?
