From all of us here at
Popular Pumpkin Science, have a happy, safe, mischievous, drunken, costumed, candy-gorged, family-friendly, slightly illegal, well-meaning and in some way personally fulfilling Halloween. This particular pumpkin (you can see it in the light after the jump) was carved by PumpSci editrix extraordinaire Susannah F. Locke, though we can't say we'd be upset if some of you all were to follow in her footsteps and give us some free pumpkin promotion on your doorsteps. Have a great weekend, everyone!
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
