What to use a giant parabolic mirror in???? I need ideas.
So yesterday I came across a decent sized parabolic mirror. It's good quality glass & it's polished nicely. I've never priced one but my dad was guessing that it's probably a $200+ mirror. I got it for $12 & I have to put it to good use. The only thing I can really think of so far is a telescope. Any other ideas as to what I could build with it?
