Make the dragon glass candy: Melt blue jolly ranchers in the microwave at 80% power for 1 minute. Microwave power varies, so be careful and adjust as needed for your microwave. If not fully melted, continue cooking in 15 second increments. When finished, pour onto a silicone baking mat and allow to set; Once hard, break into shards of varying sizes and set aside.
Prepare the cocktail: Put a glass in the freezer for about 5 minutes. Put the salt on a plate, then add 1 to 2 drops of food coloring and smear it on the salt. Mix it through until the salt turns blue, then spread it out on the plate.
Remove the class from the freezer, rub the lemon wedge around the rim of the glass, then dip the wet rim into the blue salt.
Fill one-fourth of the glass with crushed ice, then add vodka, blue curacao and the juice of the lemon wedge. Slowly mix it everything together with a spoon.
Top the cocktail with lemonade, then finish it off with a little more crushed ice if you wish.
Finally, break off long shards of the candy, and stick them in the cocktail. Enjoy!
