My standard recipe, soaking 10 Skittles for every ounce of vodka. It doesn't really matter what type of vodka that you use (because it tastes like Skittles), but I typically use Smirnoff. I soak the Skittles overnight and shake them up at least 3 times during soaking. To strain the Skittles, I use the cheapest coffee filters. 2 filters at a time (stacked on top of each other), but changing them frequently as the gunk starts to collect at the bottom of the filter.
Lemon Vodka Slush ~ 3 cups Water, 2 cups Sugar, Juice and zest of 2 Lemons, 2 cups Vodka, (Lemonade optional for mixing), Melt sugar in water, cool, stir in rest. Freeze, scrape into glasses and garnish with slices.
