Just saw these air-quality balloons on
Gizmodo and thought, "wouldn't these be kind of cool for an environmentally themed reception?" Then I thought, "Hmm, given the air quality in all too many ballrooms, maybe not." Then again, if they just measure diesel and exhaust fumes, it shouldn't be too bad. Now if they measured for mold, dust mites, and other indoor-air-quality yucks, that might be a bit more colorful.
Hey, it's Friday afternoon, why not obsess over air-quality balloons?
