Sort out skittles into the same colour.

Once in the same colour, put the skittles into different bottles, pour the vodka onto the skittles.

Give the bottles a shake and put them in the fridge, leave them for a few days, shaking occasionally.

When all the skittles are white and soft, get some coffee filters and filter the vodka through them to catch all the skittles. I filter them twice to make sure.

Once you have filtered the vodka, pour into your desired bottles. It was last for a while, although it usually goes pretty fast! Enjoy!
