Is this an Egg?

Thanks Bill, It appeared over night. And Its not an air bubble. Still waiting for my Cheese Steak : )

Swing by philly sometime and I'll take you for a real cheese steak, not those things we feed to tourists. Lol

It looks gelatinous, but no small eggs. I was thinking it may be a snail egg sac. But without the presence of eggs, that most likely rules that out.
