Making a waterfall bong...

Hey so I wanna go home after work and make a waterfall bong, however I can't seem to find any good info on the internet on what household items I can use as the bowl. Any suggestions for a quick and dirty bowl?

How is it you can't find any good info on the net? It's all out there, you just need to find it! lol

How about this one?

Although I like to make mine out of cooler bottles than just normal two liters. But work with what you got.
