Yeh i guess u got a good point there but u could always go to a hardware shop and find some different bits of piping that will connect togethor and get some rubber washers for airtightness and voila! u got a nice pipe thats custom made...wouldnt find that in any shops course the person in the shop mite be slightly suspicous y a kid is buying piping but i dont think there is much they could do apart from give a weird look haha
