In simple, fire creates heat, which creates vibration, which makes exes electrons get thrown out, and we see this in the form of light. Different salts have different amounts of electrons, and and we are able to see this as different colours.

This is just the script we used for the busk off, but it explains the science:

Welcome to the sparkly cotton ball experiment. This experiment demonstrates oxidization as well as complete and incomplete combustion reactions. 

What we have here are cotton balls, methylated spirits, zinc and iron metals as powders and an ignition source (matches) (show).

What we are going to do is soak the cotton ball in meths

Here we have some small amounts of each metal powder which Flynn will roll the ball in making it pick up some of the powders

So there are three reactions at play here.

1.  The Meths burning

2.  The Cotton ball burning

3.  And The metals rapidly oxidising

The combustion of methylated spirits is what is known as a complete combustion reaction. This is because the only products are CO2 and H2O.

Here is the balanced equation for the combustion of methylated spirits: 2CH3OH + 3O2→2CO2+4H2O.

Next

The cotton ball is also burning, but it is not a complete combustion reaction so it creates other products in the form of ashes, smoke and the charred remains

The final part of this is the metals burning. Both of the metals when heated become significantly more reactive with the oxygen in the atmosphere. This causes them to oxidise rapidly which we see as light.

Things needed:

• Teabags

• Matches

• Heatproof surface

Method:

1. Empty teabags and  remove strings

2.  Stand teabags upright on top of a heatproof surface

3. Set fire to the top

4. Watch the tea bag fly up
