What makes Floating Bath Bombs float?

Ingredients that are less dense than water, and don't pack the mixture too tightly, are the key to making sure your bath bomb floats during the dissolution process. If you are making your own bath bombs, Epson salt and corn starch are good ingredients to help your Bath Bombs float.

When you first make bath bombs or when you first start making these products at home, you tend to put as much mixture as possible into the mold to avoid fragmentation or cracking when you take out the mold.

This may work for you when creating a bath bomb, especially if you want to avoid a lot of drying time or, more importantly, something that goes into the water and floats like a brick.

What makes a Floating Bath Bombs sink? And how to avoid it?

Lack of cavitation and dense packaging, heavy ingredients will cause a bath bomb to sink when placed in the water. The packaging is softer, the use of light ingredients and light oil is more successful in floating, avoiding the feeling of sinking.

You've been making some floating bath bombs, and when you try to take them out of the mold, you find that they break.

Many times, people will mistakenly think that the reason is that the mixture not packed into the mold is not tight enough. In fact, the reason for crushing is that the formula is not binding.

Due to poor diagnosis, the reason for the next action is usually to load as much mixture as possible into the mold next time, take it out of the mold, dry it completely like a huge shell, and then find that the floating bath bomb fell disappointingly deep into the bathtub during the introduction.
