    I thought the punchline would be that he only wanted to move the table like an inch to the left. 3 Months of Work -> "Yep looks good" -> Scoots the table 1 inch to the left.

    Why do so many people brush their teeth in the shower?

    They let this thing cool for nearly a year, then polish it for 18 months. And they have to make 6 of them. Whew!

    Fun Fact: I've been in the U of A mirror lab before when i was like 15! I was one of those really cool Astronomy Camp nerds. I think i recall getting to toss a hunk of glass into the kiln. At the time I believe they were making mirrors for Keck 1 and 2

    One thing they didn't mention in the video is that the mirror was spinning for the year long cooling part. The spinning creates a parabolic shape without the need to use a mold or grind down a lot of the mirror after it's cooled.
