You can When i was about 10, we threw a snowball at a car (turned into an ice ball actually) andput a f**k off dent in it. he chased us for ages, cudnt get us though. Ooo, never ever throw a brick through a Nova GTE window with a nutter at the wheel. Ends up in his mates chasing you down and alley in their cars with baseball bats, your mat running into the side of a police van and you having to hide on a roof to get away from them... never again!! We were bored ok haha
