What do Santa’s reindeer eat? Why marshmallows, oats, and sprinkles, of course! Our Reindeer Food Confetti Poppers are sure to be a big hit with your family as they welcome Santa's Reindeer on Christmas Eve! Each confetti popper contains a special mix of "Reindeer Food" designed to be "launched" into the air. Simply remove the tamper seal and lid and use the palm of your hand to push the bottom towards the top of the popper. Try to aim at a 45-degree angle for best results.
