Melt yellow candy following package instructions. Fill one sports ball pan half with melted candy. Place in refrigerator until a 1/4 in. thick shell has formed, about 10 to 15 minutes.
Pour out excess candy; smooth top edges with a spatula and refrigerate an additional 15 to 20 minutes. Carefully unmold the shell.
If you have difficulty, place in freezer 2 to 3 minutes, then unmold. Allow candy shell come to room temperature.
