Bath bombs

                                          

We had to make bath bombs using dye citric acid and salt and some other wet ingredients

First of all we had the mixture in the bowl then we had to mix it then we chose  our colouring,then we shaped into a ball and put it in the mould. 

This happens because citric acid react to make carbon dioxide bubbles. This is an acid–base reaction, where baking soda (also called sodium bicarbonate) is a weak base and citric acid is a weak acid.

I found it easy to mix the ingredients

I found it hard to mould it because sometimes it kept falling apart

I enjoyed putting in the dye

Next time I won't put so much dye
