We have enjoyed an action packed day crammed with Science from start to finish.  Sorry if some of us smell of vinegar tonight but we did have fun.  We explored the meaning of dissolving and whether it is correct to say a solid has simply disappeared, it was necessary to eat a little candle floss to help with this.  Next we investigated how different materials when mixed together can result in a reaction.  When the bicarbonate of soda was mixed with vinegar it formed a gas (carbon dioxide).  The gas filled up the bottle and then moved into the balloon causing it to inflate.  For our grand finale we enjoyed observing the reaction of Coca-Cola and mentos.
