Here I’m showing the impression of feathers in silly putty.
This bird is the third one in the series. As I hold it, it looks like a thick heart. We can see the head starting to form and tip out. You can see the umbilical cord on the other side(look in the silly putty!)
The first picture is the egg, the wet chick, heart shape and the swan. Don’t you just want all of them! Scientists will. I hope someone will buy these from me and donate them to Science, so much could be learned!
