Last week I had my cousin’s little boy round for a few hours and it wasn’t long before he, and Mr D declared that they wanted to do some science experiments – it was a bit short notice so I opted for some easy table top science with some bubbling brew.
To create your own bubbling brew you need just a few simple household items:
- Small glasses or jam jars
- food colouring
- washing up liquid
- bicarbonate of soda
Simply fill a glass or jar halfway up with the vinegar and add some food colouring – clear vinegar works best with food colouring but normal malt vinegar is fine; you just need to add more food colouring. Add a few drops of washing up liquid to the vinegar.
Simply pour in a teaspoon of bicarbonate of soda and you’ll see the mixture bubble up and over the edge of the glass – it’s pretty impressive! You can also add glitter and small sequins to make it more magical if you wanted to. If you’re particularly crafty you could make a volcano to cover the glasses – this would look really good I am sure as the mixture comes crashing down the edge!
The children were wowed by this really simple mixture and my nephew even asked me where I had managed to get such chemicals from.
I placed our glasses into a large, deep baking tray to catch the mixture as it over flowed – so make sure you have something to hand as it could get a bit messy!
