4. Star Jelly
A gelatin like substance, the existence of star jelly has mixed responses. Some term it as a paranormal substance while others consider it a natural byproduct. There is no scientific classification of the star jelly. According to an incident reported in 1950, there was a discovery of a quivering jelly that dissolved into a stick, odorless scum when it touched by the men who discovered it. The movie “The Blob” inspired from this incident showed the jelly as an alien that terrorized a small community in Pennsylvania.
