So what did we figure out?
a. That the water level in the cup must go down/get lower since we see the weight of the cup decrease over time.
b. The water only has one place to go without a lid, and that's up and out!
So if water ends up in the air, what happens when a lid is placed on the cup!?!?! It certainly looks as if the water is getting trapped, and it can't get out! So if there's more and more water in the air...

What happens when that water is in the air?
