Pour your choice of silver or gold edible glitter onto a plate. Dip a towel in water and moisten the rim of an empty glass. Place the rim of the glass in the middle of the edible glitter and twist until entire rim is covered. Then, fill the glass with 4 oz of water and drop in 2 Alka-Seltzer® Lemon-Lime Tablets. Complete your mocktail by garnishing the rim with a lemon slice! Wait until the tablets are done fizzing, then add ice and ring in the New Year feeling refreshed.
