If you're looking to make something fun and tasty for the kids to eat, give these color changing noodles a try. It's actually quite easy! After receiving this request from their fans, Hellthy Junk Food researched how it's done and BOOM, they've got blue noodles! All you need to do is order a package of butterfly pea flowers, cook them with the noodles, and you should have the result you're looking for. For even more fun, squirt some lemon juice on them and watch them change color!
