You just need to practice in the yard (lol not in the house
) A carrot stick is not much different than any other type of whip and you need to learn how to control the end through fluid movements.
Wear sunglasses and go fling it around...Try not to whoop your own butt with it and learn how it works. You'll look like a goof ball for the first 10 minutes or so then you'll start to figure it out!
Good Luck and don't poke your eye out!!!
