Fizzing test-tubes science fun.

We had loads of fun the other day with this science experiment.
As it was a lovely sunny day I decided to take the activity outside so there would be less mess for me to clean up in the kitchen.

We set up our test-tube and put in a couple of scoops of bicarbonate of soda.



We then added some food colouring.


We then put in a squirt of washing up liquid.



We then carefully tipped in the vinegar.


The mixture quickly began to fizz and bubble up and over the test tube.





The kiddies loved this experiment and wanted to do it again and again.
