It is estimated that retail sales of candles are at $3.2 billion annually! With the broad variety of shapes and sizes, from tea lights, votives, tapers, pillars to floating, novelty, and jar candles, there is no end to the possible number of science experiments you can try at home.
As always, when experimenting with any type of flame, it is important to take safety measures into account to ensure the safety of both people and things. Here are 6 exciting science experiments that involve the use of a candle:

1. Underwater candle experiment (h/t DaveHax)
There are numerous experiments you can try at home using a candle. For this easy science experiment, all you need is a candle, bowl, lighter, and water. Watch as the inside of the candle melts away while the outside remains cool, allowing the flame to remain lit.
2. Amazing drinking candle (h/t Science with Zlife Education)
In this quick video, watch in amazement as the candle appears to drink up the water. Any kid will be in wonderment as they observe the volume change. All that is needed for this fun experiment is a few simple materials found right at home. Why do you think the water rose?
3. Cool swinging candle (h/t Coolphysicsvideo Physics)
Learn a little physics with this science experiment video. Watch as the candle begins to lose its balance when wax drips down on one side, shifting the weight to the other side. Take the time to let the candle thoroughly burn to see the full effect. Give it a try yourself!
4. Unexpected candle flame balloon experiment (h/t mathtutordvd)
Balloons are always fun and exciting, especially in science experiments. In this video, learn how you can place a balloon directly over the flame of a candle without it doing the expected – POP! This science experiment shows us how this is possible by using the force of heat conduction. What happens when the balloon is placed right over the glass? Be sure to check out the video to the very end to see the extra bonus the experimenter has in store for viewers!
5. The hidden energy of candles (h/t GAJANAND SHARMA)
In this video learn how a pair of candles can energize almost anything needing a battery. While a little more complex than some of the other candle experiments, this video shows how easy it is to power a lightbulb from a flashlight.

6. Blow out candle with carbon dioxide (h/t HooplaKidzLab)
Blow out a candle like a boss by trying this experiment at home. In this video, you will learn about the weight of carbon dioxide and how flames need oxygen to survive.
