Bob the plumber is repairing a leaking brass pipe. After careful inspection he finds that he will have to cut the pipe and sweat a new piece in place of leaky section. (Sweat is a term used to describe the procedure of using solder and a torch to mend two pieces of brass pipe together.) Once Bob gets the water shut off he proceeds to start sweating the new piece of pipe in place, but there is still some water leaking out of the pipes, which is hindering his work. Since Bob is in a hurry and doesn't have time to wait for all the water to drain from the pipes, what item found in most food cupboards or pantries could help him continue his work? (Note: This is not food he is going to eat waiting for all the water to drain from the pipes.)

I was thinking instant mashed potatos or maybe instant rice, or animal crackers. Bread sounds like a good choice though. This one was no sweat.

I knew it was bread, but that's not really a teaser. It's more of a really old plumbing trick.

I finally got a science question RIGHT!!!

i was thinking more along the lines of cauliflower or brussel sprouts. does it make a difference if the bread is rye, sourdough, or olive?

Old plumbers trick. The type of bread usually does not matter except for one type. Forget the breads with whole grain, with grain still in the bread. They will not dissolve, and will clog up your aerators.

You could do this with more than bread.............
