Anyone can put out a candle by blowing on it. According to [Physics Girl], that method is old hat. She made an educational video that shows five different ways to put out a candle using–what else–physics.
You might not need alternate ways to put out a candle, but if you are looking to engage students in STEM (Science, Technology, Engineering, and Math), this video along with others from [Physics Girl] might spark interest.
The video shows entertaining demonstrations that cover thermodynamics, fluid dynamics, and other science topics. Spoiler alert: the final method is to quench the flame with liquid nitrogen. But keep watching after that for a little mini-blooper reel, where she makes a bit of a mess and nearly burns down her studio.
Once you’ve started doing science with a candle, you might move on to thermoelectric generators, or you could do some more advanced studies.
