Here’s a sparkleball made with Party City color hard plastic cups in “white.” The maker, Carl Boro,paired them with warm white LED lights for a soft ivory pearlescence. Total moon-glow. Because of the cup’s shape, each half is built in four rings: 14 – 11 – 6 – 1 (64 cups in all.) To see how Carl does it, check out instructions for the Hard Cup Sparkleball.
“The fun part is figuring out the puzzle,” Carl Boro says. When he saw his first sparkleball at a neighbor’s, it took a while to figure out how to make one. Once he did, then the puzzle became how to make sparkleballs better. Better formulas for building the balls. Better methods for attaching cups and inserting lights.
In Carl’s workshop, there’s a drill press for making holes in cups. Cases of lights. A stash of his favorite hard plastic cups, sorted by color. Giant paperclips. Tubes of silicon caulk. A cushioned dolly to store the giant New Year’s Eve sparkle ball and plenty of hanging space.
Visiting Carl is one of the most fun things I’ll ever do in my life.
