I have posted 2 pictures. The larger of the two is what a bubbler should look like. These, you put water in (the bottom chamber only... you might want to investigate this part closely, cause wet weed sucks.) the smaller is a spoon, and in these, you put ABSOLUTELY NO WATER. you will ruin your whole bowl.

Enjoy! (by the way, I found a picture of the same bubbler I have. The woodstock. I love that thing....)
