These things (caps?) are found all over the place here in Michigan. Anytime you find one, keep hunting that park or field or island. Something was going on at least 100 or more years ago. They are made of aluminum, most are 1/2 inch diameter on the open end, if not smashed, they are 1/4 inch tall, the look like large caliber thin aluminum pellets, we also thought opium bottle caps, some of these are 3/4 inch in diameter, and have a rubber seal around the narrow waist part of them. We have searched available patent materials and pictures, typed in all kinds of "key words" and still can't figure out what they are. Many kudo's to whoever can find anything about these things......... notgittinenny
