What can I use to smoke weed?

Alright I have smoked weed before and the problem for me isn't getting the weed, its getting something to smoke it with. I have made water bottle bongs and stuff but I would like to get something like a gl water bong if possible. I have head shops around my city but heres the catch. I need something small enough to hide and keep discrete. I don't want to get anything too small that would minimize the high that I get when smoking from it. I'm just looking for a good reliable way to smoke that is easily hidden and discrete. I was looking for a water bong cause I like those the best but I don't really think there are any that are very small? Any advice is appreciated, and thank you.
