no no no .....
get a full watermelon and make a hole in it (about half an inch wide and halfway down into the melon)
then pour wodka or any preferred liquor inside and let the melon absorb it, then refill and let the melon absorb some more (until its saturated with alcohol)
then you can put the melon into your fridge and when you feel like partying, get the melon out, cut it into pieces and enjoy!
eat it above a bowl or a deep plate because the juice that drips out is liquid gold!
PS: this is also great for festivals/concerts/parties where bringing your own booze is often forbidden....
