Did you know that candles can explode?
Things I learned about candles and candle holders yesterday:
Water only makes candle fire worse because of the candle wax
Glass candle holders cannot handle extreme changes in temperature so if you....I dunno, pour cold water on a glass candle holder that's gotten so hot the flames have almost reached the overhead light fixtures...the glass candle holder is going to explode
Candle wax is extremely hard to get out of cloth
Unintentional science experiments are the most terrifying science experiments.
