Candles are a leading cause of home fires and fatalities. Soot on the walls and furnishings is unsightly, and may also be a sign of serious problems. It may also be unhealthy, as inhalation of minute particles of soot has been documented to cause health problems.
It is a popular misconception that the phenomenon of a total eclipse of the sun is a rare occurrence. Quite the contrary. Approximately once every 18 months (on average) a total solar eclipse is visible from some place on the Earthâs surface. That's two totalities for every three years.
Total solar eclipses occur about once every one to two years, the last one being in March 2015. Itâll be the first time in nearly 40 years the spectacle will be visible from the continental United States, and itâs expected to bring in a flood of viewers, so consider stocking up on some protective glasses.
