In a medium size saucepan, mix together 1 box of Jell-O, sugar, corn syrup, and butter. Cook over medium heat until it reaches a boil, making sure to stir constantly.

Remove from stovetop and carefully pour mixture over popcorn. This part is easier if your popcorn is in a large bowl, so you have plenty of room. Quickly mix the popcorn with a spoon until all the pieces are evenly coated. *Be careful, the mixture is very hot and could burn you.

Pour popcorn onto a parchment lined cookie sheet, leaving spaces in-between the pieces.

Repeat steps 1-3 for the other box of Jell-O and spoon on the finished popcorn pieces where you left open areas of the other flavor popcorn. This will give the popcorn a blended look.

Let dry for about 15 minutes and then serve!
