After rain today this substance appeared on my fence & lawn; covering 1square meter. Looks like clear jelly. Hadn’t melted in last hour. 22 degrees Celsius. Appears to have fallen from sky due to it hanging on the fence; initially I thought must have come up from the soil. Has anyone ever seen something similar or know what this is?
