While fun and luxurious, bath bombs are also expensive. Splitting them in half will double the amount of baths you can take while spending the same amount of money. Best of all, you only need only a flat-head screwdriver and a hammer to split them!

Splitting Your Bath Bombs

1
Put one bath bomb in a plastic sandwich bag. Carefully place the bath bomb in the corner of the bag, with the seam facing up toward you. If your bath bomb doesn’t have a seam, it may be more difficult to split.^{[1]

2
Put the bag on a cutting board. Ensure you are working on a flat, sturdy surface. If your cutting board is slipping around, place a damp towel underneath it to keep it in place.^{[2]

Fit the tip of a flat-headed screwdriver into the seam.^{[3]

- If your bath bomb is flat rather than spherical, carefully cut it in half with a knife.
- If your bath bomb doesn’t have a seam or is an unwieldy shape, you can crush it with a hammer and split the pieces into two bags.

Tap the handle of the screwdriver with a hammer.^{[4]

Storing Your Bath Bombs

1
Put one half of the bath bomb in a sandwich bag.^{[5]

Store them individually. Don’t put more than one bath bomb half in a plastic bag. Not only will they be more likely to bump against each other and break down, but you’ll have to cut open the bag to get one half of the bath bomb, then reseal the bag with other half.
3
Store in a cool, dark place. Put your individually-wrapped bath bombs in a plastic air-tight container or a mason jar with a lid. Store them in a bathroom cabinet or closet to keep them away from heat, light, and moisture.^{[7]

4
Don’t display your bath bombs. Though they may be gorgeous and look like works of art, you shouldn’t display your bath bombs, even if they are in plastic bags. Putting them on display can lead to oxidation, which makes the fizzy bath bombs lose their fizzing ability when added to water.^{[8]

Some might, they all contain different ingredients. If you're worried, just use lotion after using a bath bomb.

Can I just put the bath bomb in a plastic bag?

Yes, but keeping it in a container by your bath is easier and keeps it fresh for about three weeks.
