Science Facts

Water will only conduct electricity when it has an electrolyte present, when ions are in solution which will allow for the flow of an electric current.

Tap water is not pure water, even this has a very small amount of ions present which will allow the wate to conduct to a small degree. To improve the water's conductivity, one can use one of many very common electrolytes, for example "Salt", Sodium Chloride is a strong electrolyte.

"Strong" and "weak" when talking about electrolytes refers to their ability to break up into ions in solution. "Strong" electrolytes will completely break up into ions whereas "weak" electrolytes will not break up completely (although they will break up to a degree). An example of a weak electrolyte is acetic acid (AKA "vinegar"), this weak electrolyte will also allow for the flow of an electric current through water.

There are also "non-electrolytes" such as sugar which do not break into ions at all and will not allow for the flow an an electric current.

Each cell in the human body contains 46 chromosomes (or 46 DNA molecules). If you lined up those DNA molecules end to end, a single cell would contain six feet of DNA! If the human body is made of about 100 trillion cells, each of which contains six feet of DNA, our bodies contain more than a billion miles of DNA!

The energy in the sunlight we see today started out in the core of the Sun 30,000 years ago - it spent most of this time passing through the dense atoms that make the sun and just 8 minutes to reach us once it had left the Sun! The temperature at the core of the sun is 13,600,000 kelvins. All of the energy produced by fusion in the core must travel through many successive layers to the solar photosphere before it escapes into space as sunlight or kinetic energy of particles.
