Have fun with science in a big way

We're geeks. We wear black a lot. Even in the summer. It makes us highly emmissive. Not permissive. Actually, we're probably less permissive in this situation, when we're uncomfortably hot. According to Wikipedia the day we wrote this, "Black plastic might have an emissivity of around 0.95, meaning 95 percent of all radiation that hits it will be absorbed, and the remaining 5 percent reflected."

So if you go out on a cool, sunny day, fill a 50 ft. long black plastic balloon with air, and wait for its emmisiveness to heat the air inside, you will be suitably impressed. But, of course, nobody HAS 50 ft. of black plastic to make a balloon out of. Except you, now. With the Giant Solar Balloon, you can have fun with science in a big way. Just be sure you've tied on your 400 ft. of tether before you get it aloft. Otherwise you will be 50 ft. of sad.
