Outcome

Putting out fire by removing oxygen


Resources

Candles

Matches

Jug

Bicarb of soda

Vinegar

Instructions

First, light some candles.  Explain that fire needs three things:  1. spark (match), 2. fuel (wick and wax) and 3.  oxygen.  To put out a fire, you need to remove one of these.  

In a jug, put some bicarb and add vinegar.  The result will be carbon dioxide gas.  Use the jug to "pour" the gas over the flames and watch the candles be extinguished.
