If the virus that's at the center of a global pandemic spreads via respiratory droplets, wouldn't it make sense to throw all the roadblocks you can in front of those droplets?

While plenty of people still don't seem to get it, science guy Bill Nye definitely does. In a new video posted on his TikTok channel, Nye brings his trademark brand of accessible scientific experimentation to the subject of keeping society safe from the spread COVID-19.

In the video, which New York Governer Andrew Cuomo shared on Twitter, Nye uses a scarf, a face mask, and a lit candle to demonstrate in the simplest terms possible how effective a cloth covering can be at slowing down exactly the kinds of airborne particles that are making people sick.

This is great advice for the COVID-19 pandemic, but it's also sound advice in general. If you're sick with any kind of contagious illness, putting on a mask when you leave the house helps keep everyone around you healthy.

Just put on a mask, people. It's not that hard, and the world will get back to some semblance of normal that much sooner if most of us start doing it.
