TRICK Nº1: Light a Candle without touching the wick
NOTE: This trick must heave adult supervision.
What we need:
- a candle,
- matches, or a lighter
- Light the candle;
- Let it burn for a few seconds, until the wick turns incandescent;
- Blow out the candle, you will see a thin smoke "string" going up;
- Light another match, quickly, this time place it 1 or 2 in above the wick.
The candle reignited.
The explanation is very simple, but often overlooked.
First of all fire needs 3 things to burn,
- and a Ignition;
The wick burns and at the same time the wax burns, is consumed, in this process energy is released.
If you look close enough to the candle while it burns, you can see smoke, that smoke is the result of paraffin wax combustion when you bow out the candle the smoke gets bigger, this means the fuel wasn't all consumed, some of it is released in the air as vaporized paraffin. When we provide a new source of ignition- the second match- the fuel in that smoke reignite the flame that travels down to the wick, and reignite it
Transform this demonstration in a experiment
Aldo the most of the candles are made of paraffin, you can try different types of candles:
- Try to understand what kind of candle works best.
- Maybe the scented candles don't reignite?
- What happen with a gel candle?
- Beeswax candle ignite faster or slowe?
- What kind of candles burn with less smoke?
Never play with fire without adult supervision!
