1. Please help. Strange characteristics.

    I found this little guy in a parking lot.. its completely clear besides has inclusions in it, and at a certain angle you can see rainbow colors. Also looking at it from the top down it has 4 corners..when you put a light under it it illuminates immensely. Help me identify it.
  2. Double Rainbow!

    Caught this picture of a double rainbow with my cell phone camera looking east over the tree line.
