2 L of Gin or Vodka. 9 L of Tonic Water. 3-4 Bottles of Roses Mojito Passion, OR 3-4 Canisters of Pink-Lemonade Concentrate Ice. INSTRUCTIONS: Mix all ingredients together shortly before the party begins. Add ice as late as possible before drinking. Colors come to life under a black light! Just drinking some universe, no biggie. @Sarah S., this is our next get together!
