Try paper cups, a muffin tin lined with foil-type muffin wrappers, rinsed individual yogurt containers or an ice cube tray with large sections. You will have to provide your own sticks, of course! Wait until the popsicles are partially frozen to insert the sticks, or cover your "mold" with aluminum foil and gently poke the sticks through the foil, which will hold them in place.
