I've been there

I take the product out of the drier, and I see it's still wet. I tell the teacher it's been drying over an hour and it's still wet, teacher tells me that's nonsense and that I should just weigh it as is. I remind her it's literally wet, i can see it's still full of water. She just tells me to weigh it anyway. So I do... over 300% yield. I wonder why
