Birthday Party Ghost Picture

Chasta from Enid, Oklahoma sent this ghost picture of ectoplasm floating around children at a birthday party:

"I took the following picture during my daughter's birthday party in our home. There were several photos taken within a few minutes of each other, but this is the only photo that came out with this smoky-type shadows around the kids. There was no one smoking when the picture of the children in my home was taken. I have several before and after pictures of the same 'scene,' but this is the only one that came out looking smoky."
