These skulls were formed from bubbles.
Amy Dietz of Richmond, Virginia, explained, "The foam from my beer formed this skull! I had to quickly take the picture before it dissolved away. It only lasted about 15-20 seconds. Pure luck!"
In April, Giuseppe Zappalà of Torino, Italy, "found this bubble skull in a bottle with photographic development chemical" he uses!
David Naugle found this skull in ocean foam. He took this Vine video of the skull and it blowing away.
Keep sending those pictures in, we always love seeing what our skull hunters find. Anyone is welcomed to participate, it's fun and it's easy. If you see a simulacra skull, photograph it and send those pictures in to our submissions address with a little something about what it is really and maybe a little about you.
