could be the prop crashing. Try this: stick a pin through the rubber stopper, fill a pan with some water and put it on the stove at medium-low to medium heat. Swirl it around until it dissolves again (be patient it may or may not take awhile). Then leave it for a few days to see if it stays. If it doesn't take a small % of ba and add it to the vial. If you are sure it's legit then it's the test coming out and all you need to do is put it back in.
