Fishing pole and heavy line all day long. Done.
Go out and practice in the yard or get your fishing permit and practice on the water.
You don't need a slingshot or specialized tools. A spinning reel, 8 or 9 foot rod, 2 to 3 oz sinker, 50 lb test and a steel leader.
If you're a real American, you should already have all these things. Are you, a real American?
