Light a Candle without touching the wick

This week we will explain the magic tricks in the video "Top 10 quirky science tricks for parties" we saw here.

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

How to:

1. Light the candle;
2. Let it burn for a few seconds, until the wick turns incandescent;
3. Blow out the candle, you will see a thin smoke "string" going up;
4. Light another match, quickly, this time place it 1 or 2 in above the wick.

What happened?
The candle reignited.

Why?
The explanation is very simple, but often overlooked.
First of all fire needs 3 things to burn,

1. Oxygen;
2. Fuel;
3. and a Ignition;

In this magic trick, oxygen is all over, the paraffin is the fuel and the lighters the 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? 

Note: The smoke produced during a fire tells us about combustion efficiency. A flame with a great amount of smoke means a low efficiency combustion- many of the fuel is not burned-, on the other hand a flame with "no smoke" means a great efficiency combustion- almost all the fuel is consumed during the fire.

Et voilá!
Never play with fire without adult supervision!

Super Restless Minds- magazine box with wooden fruit / vegetables box

This is a Super restless idea from Celena, convert a wooden fruit / vegetables box into a magazine box, all we need is the box, paint and varnish, some materials to reuse along with lots of imagination (from here)

What we need:

• wooden box, similar to those used in grocery,
• acrylic paint, any color you want,
• brushes,
• varnish,
• sandpaper,
• old newspapers, to cover the floor,
• old rag, to clean your hands and the brushes,
• water, to clean the brushes,
• plastic caps, from water bottles or yogurt, you will need about 6, depending on the box size,
• fabric, to cover the plastic caps, you can simply paint them,
• nails or super glue,
• felt.

How to:

1. Sand the box, to avoid injuries;
2. Remove all the wood dust from the box, otherwise the paint will not fix to the wood;
3. Paint all the box with a base color, Celena used black;
4. Paint some details, Celena painted some flowers;
5. Leave it to dry for 3 or 4 hours;
6. Varnish;
7. Paint the plastic caps, Celena used fabric;
8. Count how many boards your box has on the base and use 1 cap for each board/side, Like in picture;
9. Nail or super glue the cap on the wood board;
10. Use 1 circle of felt on each cap to prevent scratching your floor.

Thank you Celena!

Et voilá!
