1. Melt sugar, without stirring, in a saucepan over medium heat for about 5 minutes, watching constantly to make sure it doesn't burn.
2. In a large bowl, pour melted sugar over top of popcorn. Mix popcorn with a spoon and cover thoroughly. Reserve some of the melted sugar for later.
3. While still warm, roll the popcorn into balls and place on wax paper. It's a little hot, so use plastic gloves if needed.
4. Dip lollipop sticks in the leftover melted sugar and push into the balls.
