Loads of fun with my boys - Do All Outdoors Mega Boom Stainless Steel Target System

I first bought one and loved it so much I bought 4 more. I have teenage boys and the thought of tannerite is just too dangerous. These things are a lot of fun. The 2 liter bottles sound like a large pipe bomb. Every time we explode one we just crack up. Had the boy scouts shooting at these. Pumping up each bottle for a fresh target takes them about 5 minutes - I counted about 65 pumps with their air pump to hit 120lbs of pressure for the 2 liter. The boy don't mind. In fact now they save all the 2 liter bottles they can since they can't stop doing this. Use a pump pellet gun cause BBs bounce off. We even added some color chalk in the bottle for effect. I had one buddy use a compressor to fill with air but you need to be careful if you do that. You don't want to overfill like he did. Yes his ears were ringing but no one can get hurt from a "popping balloon" . I bought the metal base one as opposed to the poly carb base.
