This rainbow coloured fizzy hexagon is large enough for 2 baths. The best thing about it is the beautiful woody smell that lingers long after. It is very fizzy and creates beautiful rainbow coloured water. When it shrinks to half its size I take it out the water to use for a 2nd bath. Very earthy, woody and refreshing too...

Love the show with all the colours, but then the water colour is disgusting. I just don't like bathing in bathwater that looks like a very grubby cub has bathed there who has just got back from camping and not washed for a week.
My summary of this ballistic would be as follows
10 minutes fizzing around looking pretty

10 minutes sitting in bathwater that resembles sludge colour

10 minutes cleaning up the bath after from all the glitter....

I loved this beautiful bath bomb! It turned the water a lovely dark green that reminded me of the sea. When I put it into the bath, as it fizzed, The Experimenter created many colours that made me think of a rainbow! I have to say that it smelt incredible! My favourite bath bomb so far!

My partner got me this (along with other things) for my birthday.

It's shape and colours are very appealing to look at and hold, and it gives off a subtly sweet aroma.
Once dropped into the bath it began to spin whilst producing a vibrant foam of varying colour. The bomb lasted a good several minutes but did struggle to stay afloat after the first minute, diminishing in visual.
The midsection of the bomb takes a while to dissolve and can be used as a make-shift pumice stone to help on tough skin.
When fully dissolved, the bath turns pine green and has a subtly sweet scent.
