A moment of science

As we all likely know by now, Mr. Wizard recently passed away. In order to honor his memory, rebecca from skepchick has proposed the we all engage in a 'moment of science'. Watch the video below (thanks to astropixie, another member of SUGAA for pointing out the video), then make a short science video and post it to youtube as a response. Surely someone out there has some raw footage of interesting projects they've worked on that could be gussied up into a science demo with a bit of voiceover work (say... the effects of gravity on pumpkins, or somesuch). I'm drawing a blank on what to do, but mayhaps I'll come up with something in the next few days and film it over the weekend. I urge you all to do the same!
