Mine aren't exactly like these, which I like. As usual I was on a "use what you have" budget so I did just that, used what I had. I washed out a few different sized soup, spaghetti sauce and corn cans and sprayed them Dover White. After the paint dried I got creative with some foam brushes and acrylic paint. Colors of choice: Navy Blue and Christmas Red.
My sister gave me a bag of odds and ends wooden shapes a while back and among the odds and ends were these cute little wooden button stars. So I painted them red, white and blue. I tapped a little hole into the top of the can (really the bottom, I flipped them over for this project) with a small nail and hammer. Then I cut some wire and twisted it up for the "fuse."
I used just a touch of hot glue to put the star on the wire and the wire on the can and here is the finished product. Mine aren't as tall and skinny as the ones at the store, but like I told Tall Man, "Tall, skinny fireworks are sissy fireworks. These are MAN fireworks! (enter Tim Taylor grunt.)"
