Budget_Roof1065: “Cap bomb. I must have gone through a hundred of those as a child in the 70’s. Twist the top, put a paper cap in, twist the top back down, throw it up in the air. When it hits the pavement, it makes a bang.” aztecforlife: “We stuck caps (little explosive wad) in them and they pop when you throw them. Probably removed from the market around the time lawn darts were deemed hazardous.” JimiTrucks1972: “I had a bunch of those. Man I can smell the picture. God I loved the smell of those red caps.”
