Mystery Substance Found in Desert...Evidence of UFO??

'They're out of this world!': Mysterious purple spheres found in the desert spark speculation

Tuscon locals are baffled by the appearance of thousands of tiny, purple sphere that have appeared in the middle of a desert.
Geradine Vargas and her husband discovered the strange collection Sunday while on a walk.
'We were taking photos around the area and we just.... I mean, how could you miss this?' Geradine said. 'It was just like glittering in the sun.'

 

Mystery: No one seems to what these purple spheres in the desert are where they came from

 

'It's just one of those things that you've never seen before. 'Some of the spheres were watery and others translucent. They were completed isolated from the rest of the desert terrain.

Possibilities: Some have speculated that the spheres could be a slime mold or jelly fungus or a man-made product for plant hydration
 

'We did email a friend of ours who's a zoologist, but she didn't know,' Gerardine told reporters. 'I mean, she didn't seem to recognize what it was.' The news station checked out the spheres, reporting that they were like 'gooey marbles that ooze out a water substance when squished.'

Isolated: Everyone from botanists to tv crews has speculated on the sphere's origin

 

Darlene Buhrow, director of marketing for Tucson Botanical Gardens said that after speaking to a botanist learned that, if the spheres are naturally occurring, they could be a slime mold or jelly fungus.
Other suggest they are a product, like Deco Beads which are small, colored, water-filled balls designed to keep plants hydrated. Though that does little to explain why thousands of them would have been put in the desert.
