If you want to waste a couple bucks and explore your tech side. You can buy something like this. Engine snake camera. (I'm not recommending this one, there are plenty of these types of things nowdays so look around). Doubles as a home colonoscopy (kidding!!! yikes). Again I don't recommend this one. hahaha
