Hold the flame close to the candle's wick, but don't touch the wick with the flame. Light the candle again then light another match. 5. It works best if you wave it in the smoke. This demonstration takes a little bit of practice to get right (see Implementation Notes). Part of the show Human Origins and Migration. The heat sustains the reaction by melting more hydrocarbon fuel and by creating a convection current that draws fresh air, including oxygen, up to the base of the flame.

Chemical reactions If you touched the wax vapor (white smoke) with another flame, the candle should have immediately lit up again.

When you did, have you ever looked closely at the flame? Can eating from silverware cause argyria? Making sense of secondary science: Research into children’s ideas (Routledge Education Classic Edition Series). Download PDF

Light the candle and wait until it is burning well and has a glowing ember at the end, it works better when the wick is too long. The weak flame can also indicate, on a figure candle, that the subject is losing the battle. A Jumping Flame This is an attention getter. Lighting the vapor is enough to get the candle burning again. You are too involved-step away for a time.

0: 1. I deserve love and goodness. Covid-19: saving lives vs saving the economy? Is it the wick, the solid wax, the liquid wax or something else? In this activity you will light some candles to find out—no special occasion required! Scientific American is part of Springer Nature, which owns or has commercial relations with thousands of scientific publications (many of them can be found at, Wet sand (or another non-flammable substance to hold your candles up—you could also use cake or a cupcake!

Students can, of course, often identify that air is needed for things to burn, but only rarely can they explain how it functions in combustion. If your candle flame burns firmly: Is that a good sign, because it shows that all power and energy will be used for the purpose. What does burning mean? Hold it there for about a second.

Start a Discussion, Though the candle flame is a familiar example of a combustion reaction, neither candles nor combustion are well understood by most people (find out by asking someone to explain why the bottom of the exposed wick of a partially burnt candle is unburnt; see Figure 1). 1978. Prepare your wet sand or other non-flammable base material in the dish or bowl. Jumping Flame and Dancing Candle Fire Experiments IncredibleScience. The overall combustion of candle wax can be represented by a chemical reaction (see combustion reaction in Online Supplemental Materials), in which atoms are rearranged into new compounds with properties different from those of the starting materials. 0: 3. Simon Quinnell, from the National STEM Learning Centre and Network, shows how to carry out some ‘magic’ at the Christmas dinner table using a candle and a match. I am successful.

A Jumping Flame Observations and Results Clear your thoughts. A candle consists of a wax cylinder with a wick through the centre. The weak flame that goes out means that you’ve missed your target altogether, start over. Fire-Fighting Foam, from Scientific American Light the candle and wait until it is burning well and has a glowing ember at the end, it works better when the wick is too long. Steadfastness, patience, and perseverance.

This can show that you are facing heavy opposition and must redo the magick several times in order to overcome the power you are facing. The issue is too emotional.

If you apply a heat source quickly enough, you can ignite the wax and use that reaction to relight the wick of the candle. An understanding of candles, and combustion more generally, can provide insight into everything from car engines to climate change! After burning, the bottom of a candle’s exposed wick remain unburnt (white arrow). A Candle Seesaw Balancing Act, from Scientific American Michael Faraday’s lecture for children on the chemical history of a candle, Royal Society of Chemistry’s jumping candle flame activity, Combustion reaction, shown with a simple hydrocarbon, Chemistry Can you tell?

Then when a match is placed near the wick, the flame appears to jump to the candle to re-light it. Colours can also show that the question may be best answered at a later date. Have you ever looked closely at the flame? However, mass is close enough to being conserved that our measuring devices can’t detect the difference.).

A good sign of success and love. Through the center of the wax runs a wick, which is usually made from cotton or other material that can absorb liquids well. The lesson that follows will work best when students understand what a chemical reaction is.

Ask students to try explaining these results.

They should almost touch each other.
