Thanks Danger! Say I buy a cheap buzzer off Amazon (with the two wires exposed, see picture below). Would I need to add a battery to power it and create the buzz?

For my class project, the liquid that needs to be detected is water. I am hoping to do this as inexpensively as possible (my dad is going to help me pay for the parts so I can build one for presentation). I am hoping to hook the pad up to a buzzer so it makes a loud noise as soon as you spill...

Hey all, For a school project, I am trying to design a pad (placed on the floor) which can detect liquid and make a loud buzzing sound immediately upon the detection of the liquids. Any ideas?
