SCIENCE EXPERIMENT: Hot Water on a Cold Day

While the cold weather certainly isn't pleasant, it does allow for some cool science experiments! 

You probably have all seen the video on Facebook or social media. Taking a cup of boiling water and throwing it into the air and watching it turn into steam...

So what's the science behind this?

It all comes down to how much water the air can hold and how cold the air is. Cold air doesn't hold a whole lot of water. So what is actually happening is when you throw the water molecules in the air, the air isn't able to hold it- creating a vapor cloud. 

If you want to try this at home, there are a few things you should know. You are working with hot boiling water and not all of it evaporates immediately so you want to be very careful to not get boiling water on someone. The other thing you need is cold, dry air. This will only work well if the temperature is in the teens, single digits, or lower.
