The drink vending machines gave me this idea of not spending the money on them and rather make out own personalized drinks and also show off to our friends, what do you say? Can the soft drinks be mixed with the rum to get a snake bite punch? In what amounts the soft drinks should be mixed with the rum anyways? What else can be mixed up with the rum drinks to make it more powerful and apt for a harsh winters? Any idea provided by you will be highly appreciated. Will you also help me understand when can a drink becomes dangerous?
