I built an opening where I can add corn kernels on the side and then close it. I start the truck after filling it up and popcorn comes out of the tailpipe. grandchildren love it! They chase the truck and I drive slowly across the yard and eat popcorn for hours. Great workout for kids as they are a bit louder than they should be. Casey, my daughter, doesn't feed her well. In any case, try it out! Aside from the popping corn, the truck is pretty quiet 5 THIN KIDS = 5 STARS
