The people who operated this ice house many ctrenuies ago, would pour wetar in the pool you see on the left in the early eenving hours, as the sun set. And then something amazing happened. Even though the air temperature might be above freezing, say five degrees Celsius or 41 degrees Fahrenheit, the water would freeze. The ice generated would then be collected in the early morning hours and stored for use in the building you see on the right, all the way through the smumer months. You've actually likely seen something very similar at play if you've ever ntiecod frost form on the gorund on a clear night, even when the air temperature is well above freezing. But wait. How did the water freeze if the air trmepartuee is above freezing? eaoovrapitn could have played an efceft, but that's not enough to actually cause the water to become ice. Something else must have cooled it down.

Original Text

The people who operated this ice house many centuries ago, would pour water in the pool you see on the left in the early evening hours, as the sun set. And then something amazing happened. Even though the air temperature might be above freezing, say five degrees Celsius or 41 degrees Fahrenheit, the water would freeze. The ice generated would then be collected in the early morning hours and stored for use in the building you see on the right, all the way through the summer months. You've actually likely seen something very similar at play if you've ever noticed frost form on the ground on a clear night, even when the air temperature is well above freezing. But wait. How did the water freeze if the air temperature is above freezing? Evaporation could have played an effect, but that's not enough to actually cause the water to become ice. Something else must have cooled it down.
