Today I Learned: 1) The gauzy, veily stuff used to make wedding dress trains and tassles and veils is called "tulle". 2) Sodium and potassium have unusually low melting points for metals, at 98°C and 63°C, respectively. You could melt both of those in a pot of boiling water, easily. I wouldn't recommend it, though, as both would explode on contact with the water. I guess we never see either as a raw metal very often. 3) Operating costs for an aquarium with ~10 full exhibits is, order-of-magnitude, several tens of millions of dollars per year. Roughly half of that money goes to personel costs. This assumes that the budget of the Aquarium of the Pacific is typical for an aquarium of its size. Source: http://ift.tt/1Rfvyxp
