Auzas, i just use the Hair Dye/Spray. Its like 50p here. We can unscrew the tops, So we can refill easily.
Once, me and a freind stole 2 gold spraycans from the Schools art cupboard. Hes walking to a wall and he starts to spray. Hes like AAAAGGGHHH and im like wtf. I looked at his face and he sprayed it the wrong way lol.
