South Burlington middle school teacher Greg Wolf has been doing demonstrations to illustrate scientific principles to his students for more than 30 years. But now, his interactive lessons are getting attention — a lot of attention — outside of his classroom. 

Fifteen months ago, the science teacher started a TikTok account under the name Wolf_Science. He’s used it to teach about everything from how siphons work to whether Double Stuf Oreos are really double-stuffed. Along the way, he’s amassed almost 300,000 followers, and three of his videos have been viewed millions of times.
