Practicing for demo. Hmm, I may ask for a student volunteer, otherwise I’ll look like a crazy scientist after 8 presentations!

I’ve been told that my presentations to students get pretty animated. Doesn’t look like this year will be any different. Tomorrow, I’ll be demonstrating Electrostatic Precipitator to nearly 400 school kids. They’ll divide into 8 groups spread over the morning. I predict lots of funny faces and a bad hair day!

My 2013 presentation on Hydrophobic Soil. Thanks, Tim (The Forester Artist) for the fun shots.
