Hi,

I like making bath bombs, and have made some good concoctions so far.

In the last year, Lush released some new bath bombs, including Twilight and Fizzbanger and Dragons' Egg. These new bath bombs seem to last for ages, fizzing away, and spinning around and swirling pretty colours.

My bath bombs fizz away at a fairly normal rate- similar to most of the older bath bombs Lush make.

I'm interested in finding out how to make mine fizz slower. Knowing how to make the colours do the pretty swirl thing might be nice too- though I think that has to do with the consistency of the centre of the bath bomb, possibly being less dense than the outside, so that once it fizzes open, this makes it spin.

I know bentonite clay makes them harder. Does this also slow down the fizzing process, so it lasts longer?

Does anyone have any ideas please? Thanks.

Hi,

The outside shell of the new bombs foams rather than fizzes and the centre will dissolve long before the shell is gone entirely. There is a foaming agent added to the regular recipe (see ingredient list) for the shell. There might be a bit less citric acid than usual in the shell as well. The centre seems to be a regular bath bomb recipe which fizzes instead of foams.

Ok- so the cocamide and sls go in the outside shell with less citric acid, and the inner section has more citric acid/cream of tartar?
