Day 50 - Bead bubble

So I'm walking to the door this afternoon and catch a glimpse of red in the small flower bed by the front step. I bent down to see what it was and found this tiny little bead lying there. Wondering where it came from, I picked it up, brought it inside and absent-mindedly dropped it in the glass coaster sitting on the table.

Then, the more I looked at it, the more I thought it might make an interesting photo... the tiny little bubble inside was intriguing.
