I really thought it was a light bulb at first and then I looked at other people's comments and they said it looks a fire extinguisher bomb and I looked it up and it looks exactly like that
Thanks for giving me an idea of what it is. I don't think it had a seam on it and the top had been taped but on the top of the sphere it almost looked like a glass stopper.
The top cap was a hard plastic, but on the top of the sphere it has what looks like a glass stopper in it. The base has nothing on it and it is rounded so it can't sit alone. This is the bottom. Yes it does have a side seam and bottom seam
