10 Science Myths Debunked

4. Water Conducts Electricity

Most of us have been well versed about the dangers of electrical appliances near bodies of water, due to its apparent conductance of electricity. However, water itself is not actually a conductor. When an atom has more electrons than protons it has a negative charge, when it has more protons than electrons, it has a positive charge. Atoms prefer to be neutral, so swap electrons until they have equal numbers. This passage of electrons creates a flow of electricity. Water molecules have no charge on their own, so they cannot swap electrons and create this flow of electricity. However, this only applies to purified water. When water is impure it contains salt and other minerals, which allow it to conduct electrical charges. The water from your taps might look and taste clean, but it€™s not pure enough to be safe around electrical items €“ so stay sensible with the appliances!
