10 Science Myths You Probably Still Believe

7. Water Conducts Electricity

Whilst it's probably not a great idea to take your toaster into the shower with you, water is actually not a great conductor of electricity.

In fact, the conductivity of water is based on how many impurities it has in it, as it is actually there that are conducting the electricity. Seawater, for example, is an excellent conductor of electricity due to its high salt content, but distilled water that has had all of its impurities removed will act as an insulator at normal voltages.

Tap water, although it tastes fresh, also has impurities in it and will conduct electricity, which is why it is still a bad idea to use electrical items in your bathroom.
