The Snorkel Bowl is pretty phat. This is the first bowl that I have ever used and I was surprised at how well it worked. This will not cost you that much money, and most likely you have all the parts at your house.
Here is what you will need to make it.
Some kind of bowl, not a socket, with a screen from a sink. Don't even try to use this unless you have one.
Something to poke holes with.
Some caulk and maybe rubber cement, (something to close off the other end of the snorkel), or you can just use your hand as the carb and not close off the end.
A couple hours.
Well, first of all, you dont even have to use a snorkel for this one, you can use anything that is a long tube, but a snorkel works pretty damn well. First remove everything off of it, so you only have the long stem part. Then make a hole at one end, and use like a knife, and keep slowly making the whole bigger, untill you can fit a bowl in there. Try to make it airtight, but if you have to, wrap some tape around it. Also, if you want, you can add a carb, but you don't need one, it still works fine without one. The last thing, is to cover one end of the snorkel. Now if you want you can cover it up with some caulk, but you can also just cover it with your hand, light it, then let go, it will act as a carb. Then, just pop a screen in, a little greenery, and spark it.
