I got a small piece of LR with a few bubbles on it. im trying to get a picture to help you but im having a bit of trouble getting a good picture. the bubbles are clear and soft and appear to have water inside of them. the largest of them has some green debris that float around inside. there are about 5 and vary in size from about 2-3 mm to the largest being around 10 mm. Any thoughts or ideas gang?
