Making Bath Bombs.

 Last week in Science we made bath bombs for mother's day.

 We observed Mrs Bava make the powder and tell us about the reaction and that only reacts when you add water the class each got one or two boulds I got two so I dyed one blue and the other I dyed it yellow I had to mix the dyed in one at a time the yellow wasn't really coming out very bright 

The reaction;

When a bath bomb comes in contact with water, the baking soda and 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.

Once the bath bomb dried the blue was very spotty but the yellow was very nice and not spotty.

I enjoyed giving it to my mum afterschool for mothers day

I found it easy to put the powder into the mold because it was easy to mix with the powders.

I found it hard to make the power have the right amount of water because I put to much in so I was mixing but it keeped fuzzing up so I had to pat the powder down.

I enjoyed the Bath bomb once I got it because it was very nice looking with the to colours mixed together.

Next time I will try put not as much water so it won't fuzz up as much.
