Volunteer and get a t-shirt!

My deadline to order shirts for DC candy experiment volunteers is coming up this week. If you'll be anywhere near DC April 27-29, and can spare a few hours to help teach kids really awesome candy science experiments, please contact me before Thursday! (If you contact me later, I'd still love to have you volunteer, but I might not have the right shirt for you.) Even if you can't volunteer for us, please come see us at the USA Science and Engineering Festival at the Walter E Convention Center in Washington DC, April 28-29. We'll be doing some great experiments, including dropping Warheads in water to watch them bubble, and squashing marshmallows to make them sink. Plus you'll get to try hands-on activities like playing soccer with robots, or examining everyday objects under an electron microscope, or making flubber. And don't miss celebrity presentations by the Mythbusters team, Bill Nye, and Theodore Gray (who designed my favorite periodic table.) It's coming up--we'll see you in 4 1/2 weeks!
