We all know that sending real fireworks in the mail is illegal. And if you didn’t, now you do. However, don’t let that stop you from mailing these festive Fourth of July treats! Start with Lifesavers, Mentos, or other round candies that can take the heat. After that, all you need is construction paper, wire and glue to create some completely legal (and delicious) firecrackers!
