Keep kids active toward the end of your party by letting them make and assemble popcorn favor bags for guests. To create these, you’ll need brown paper bags, kid’s scissors, a hole punch, colorful string and markers. Set up a tub of popcorn on a flat, level surface such as a kitchen counter or dining table; then create an assembly line. Assign each kid a specific task such as measuring and adding the popcorn, cutting and attaching the string, punching holes in tags, writing names and/or handing the bags to the guests.
