We gathered up the last remaining bits of snow this afternoon to make a Baking Soda Volcano.
I placed a small glass jar in the centre, with the top level with the top of the snow.
How to make a snow volcano
What you need
2 spoonfuls of baking soda (bicarbonate of soda )
1 spoonful washing up liquid
a few drops of red food colouring
30 ml vinegar
Method
Add everything except the vinegar to the water bottle.
Stand back, get ready……add the vinegar and watch the eruption! If it doesn’t work so well, add a bit more washing up liquid and vinegar.
I loved how easy this was to make and how great the red looked against the snow!
What do you think of our Baking Soda Volcano?
The Science bit
Vinegar (an acid ) and bicarbonate of soda ( an alkali ) react together to neutralise each other. This reaction releases carbon dioxide, a gas which is the bubbles you see, these bubbles make the washing up liquid bubble up to give the reaction shown above.
You could also try making a multi-coloured snow volcano.
