Iron

Iron bars appear in Airfield Chase, Smuggler's Plane and Angry Birds Space. If you hit it, it will make a "ching" sound. Iron is a hard material to break. Chuck, Terence, Bomb, Matilda, Mighty, Al and Bubbles can break the iron. However, in Angry Birds Space, iron is more fragile. In Angry Birds Star Wars, Chuck "Ham" Solo can break iron with 3 lasers. The lasers will reflect so they can hit other Pigs. It serves as steel in Angry Birds Star Wars because once shot with lazers or damaged by a lightsaber, it will appear inside of the wood/glass/hard metal
