And another question, does it hurt to put a candle out with your fingers?

Your fingers in this case. Now, the bit of wick in question is comparatively tiny, so even though it's hot, it can't do that much damage, but it can be enough to cause painful burns (especially on your fingertips, which are packed with nerve endings). What is candle tunneling? Tunneling happens when only a small portion of the wax around the wick melts while the candle is burning. Instead of having the entire surface of the wax melt evenly, it will appear as though the flame is burrowing into the candle and creating what resembles a small, vertical tunnel - hence the name.

Regarding this, why do you put a glass of water next to a candle?

The burning candle heats the air above it, including the air that goes into the glass. As it does so, the air in the glass cools, and as it cools, the air pressure in the glass falls below atmospheric pressure. Water is drawn into the glass until the pressure is equalised. Why did my glass candle explode? Since the hotter area of the candle is generally the center and the wax pool becomes a little cooler as it spreads out to the edge, the hot splattering water/wax, and fire combination reaches out towards the glass container causing the candle to break or "explode."

Can I put lid on candle after blowing out?

Another smart trick? Candle jars usually come with a lid, which can be used when it's time to extinguish the flame. Simply blow out the candle gently and then cover immediately with the lid to prevent dust and dirt from getting on the wax and wick. It also helps trap the smoke. What is the healthiest type of candle? Beeswax candles are the healthiest choice in candles. Made from the caps of bee honeycombs, beeswax candles burn clean, are very long-burning, and give off a pleasant natural fragrance as they burn. Beeswax candles are dripless when burned properly, and release negative ions which help clean the air in a room.
