Cocktail Builder

So, I have leftover alcohol in my cabinet that I came across when I was making space for other things...what to do with it. It's not as good by itself. What if I mix it? Hmmm. Cocktail Builder will be my friend. All I have to do is input the beverages that I have and it will tell me what I can make. What fun! But what I realized is is that I have to buy more stuff...I don't have enough! Since we have a no alcohol policy for the library, I can't see any way to use this in a library setting. Hmmmm.
