Scientists at Harvard University have figured out a way to use these petite pouches as an inexpensive alternate to glass test tubes and culture dishes. They even ran glucose tests on artificial urine and anemia tests on blood, all with the samples sitting inside bubble wrap.
Any eclipse is worth seeing. A total eclipse — where the moon completely blots out the sun, where day turns to night, where solar flares ring the moon's shadow like a crown of flame — that's the eclipse everybody wants to see, the alpha eclipse that eclipses all the other eclipses.
