First, we fill the glass with tap water to the top. We clip the 9v battery to the clip, and then unclip it after ten seconds. Write down the energy in volts that is written on the volt meter after ten seconds. After thirty seconds, write down the amount of volts. Keep writing down the voltage in increments of thirty seconds until five minutes have passed. Next, dissolve 50 ml of salt into tap water, and fill the glass to the top. Clip the battery to the clip for ten seconds, and then remove it. Record the voltage in the same manner as before. Put 50 ml of vinegar in normal tap water. Clip and un-clip the battery, and measure the different voltages in the same way as before. Mix in 50 ml of soap into normal tap water, Clip and un-clip the battery and write down the voltages in the same way as before. Finally, fill the glass with distilled water. Repeat the battery process. Record the voltage as well. Make sure to wash the glass after every experiment.
