We have had a lot of fun with this little Christmas science experiment. It is so simple, it is definitely worth a try if you have a few minutes to spare and want to give the kids a good laugh.
Here is what you will need:
- A small jar, or similar, decorated as a snowman. We covered ours in modeling clay and painted it but you could get the kids to paint a jar or decorate it as they wish. (The jar I used here is 100ml volume but you can alter the size.)
- Some water (I used 40mls)
- Washing up liquid (I added about a tablespoon)
- Baking soda (also know as bread soda or sodium bicarbonate, but NOT baking powder… they are quite different)
- A teaspoon.
- Something to stir with
- White malt vinegar (I used 40mls)
Here is what you do:
- First add the water and then the washing up liquid.
- Next add a heaped teaspoon of baking soda.
- Give it a good stir.
- Add all the vinegar, quickly, stand back and watch’s the poor snowman’s brains explode… that’s got to hurt!
- And once your poor snowman has recovered, you can give him a quick rinse and do it all over again!
