Basically there are two metal panels: one of copper and one of zinc. Any person who has some idea about physics knows that these two metals are usually used to make batteries. They make look small but they produce enough electricity for the clock to work. After physics comes the chemistry part of the clock, for an electrolytic cell to work you need three things: and electrolyte, two dissimilar metals: copper and zinc and a electric load.
If you do not know what an electrolyte we are here to tell you that it is a liquid in which metals are usually suspended in order to produce electricity. What this liquid does is allow the ions which are produced to move freely. In the Bodel water clock the water is the electrolyte, the liquid which allows to circulate and make the clock work. You may be wondering what the lemon drops are for, they are used to increase the performance of the clock, to make the water a better conductor.
