We gathered up the last remaining bits of snow this afternoon to make a Volcano.
I placed a small glass jar in the centre, with the top level with the top of the snow.
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 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.

ooh I like it with the snow…I like it even more that it’s outside!
I would have never thought to do this outside with the snow… what a fun idea! I love it!!
Right if I can get a snow day tomorrow I am trying this out!
I was going to get out to do this with the last of the snow today, but it’s all muddy
I love this version of the classic volcano! Will have to give it a go with my kids!!!
Now this is super fun and there isn’t the heart break of destroying a papier mache work of art
Love this. Just need to get some more snow. We had a dismal show this year
oh no, I hope you get some soon. x
Going to try this next Winters, I think my kids would love to do this.
