Bubbling Cocktails

The beverages (actually kiwi-based refreshers) look pleasingly poisonous in any glass, but chemistry flasks -- available online from lab suppliers for a few dollars apiece -- suit them best. 1. In a glass measuring cup, pour 1 cup boiling water over 1 cup sugar. Stir until sugar has dissolved; refrigerate until cool. 2. Puree 2 cups packed mint leaves (1 small bunch) with 1/4 cup cooled syrup in a blender. Add 6 peeled, quartered kiwis, and blend until just smooth. Add remaining syrup. 3. Pour through a cheesecloth-lined fine sieve into a pitcher; discard solids. Stir in ice and 1 liter sparkling water or club soda. (For a cocktail version, add 1 cup vodka.) Pour into flasks, and serve with straws. Makes 8 drinks. Source: http://www.marthastewart.com/
