Remove all the green skittles from a pack of skittles. Place in a vodka bottle and ensure the cap is securely fitted back on. If you put the vodka bottle through one cycle of a dishwasher on the top shelf then the skittles dissolve into the vodka without any trouble to the vodka or your dishwasher. If you don't remove the green skittles then your vodka goes a horrible brown colour and the taste deteriorates.
Add the 'Skittles vodka' to a pint glass.
Add 2 shots of Blue Curacao
In Britain we use VK Orange to top up (an orange flavoured alcopop), alternatively you could use orange juice and a dash of lemonade.
Don't try too much, it can get sickly after a while. Packs a punch though and goes down well at first.
