Woo Hoo! I finally managed to make a good batch of bubble bars. My first batch were too dry and crumbled into pieces, although they still made great bubbles. I let Girl Child have them for her baths. (She is definitely one of those girls who loves a good bubble bath.) These little guys look similar to bath bombs but when you crumble them into the water, they make lots of bubbles for a glorious bubble bath. They are more difficult to master than bath bombs. Plan on experimenting a few time before you get it right since your local humidity can really affect the results. My house was experiencing low humidity when I started making these, so I really did need to add more liquid than the recipe called for, even though the recipe warned not to do that. They dried out in about 2 days even with the extra liquid.
Because I was making these in December near Christmas time, I decided to go with peppermint scent using essential oils. You can certainly change that up to make them any scent that you desire.
- 1 cup SLSA
- 1 cup baking soda
- 1/3 cup cornstarch
- 1/3 cup cream of tartar
- 1/3 cup glycerin
- 1 Tablespoon almond oil, olive oil, or other oil
- 1 teaspoon water
- optional – 20 drops essential oils – I used peppermint
- optional – colors
- 2 mixing bowls
- parchment paper
- rolling pin
- surgical mask *
- gloves *
*SLSA is very dusty and can irritate your lungs if breathed in, some people have skin that is sensitive to some ingredients
While wearing your mask, sift together all of the dry ingredients into one bowl. The SLSA powder is very dusty so be careful not to shake or mix too vigorously.
Mix the wet ingredients in the second bowl. Stir until the mixture starts to thicken, which means they are thoroughly mixed.
Wearing gloves, add the wet ingredients to the dry and mix well with your hands. The mixture takes some work to get to the right consistency. It should feel like a dry cookie dough. If it is too dry and crumbly to roll out without cracking, add more glycerin.
If you want to add color, do it now. Many people like to do 2 colors and roll them together to make a spiral. To do that, divide the mix in half. Add your first color to one half and your second color to the other half. On the parchment paper, use your rolling pin to roll out the first color into a rectangle about 1/4 inch thick. Place the second color on top of the first and flatten with your hands or rolling pin to fit on top of the bottom layer. Using the parchment paper, start on one long side and start to roll the dough onto itself like a jelly roll or sushi. Keep going until the whole thing is a log, pressing in gently to compress. You want the log to be tightly packed without squishing the swirly design. Cut into slices 3/4 -1 inch wide. Allow to dry for about 3 days before using.
Rather than rolling out spiral bars, I decided to cut out shapes. The process was very similar to making sugar cookies. Roll out your mix, cut out the shapes, then gather up the leftover mix and re-roll. Repeat as needed until all of the mix has been used. I used snowflake cookie cutters, although they ended up looking more like stars. I topped them with a sprinkle of blue colored sugar to make them look more wintery.
I had some leftover mix that was not quite enough to cut into another snowflake, so I made that one round and added red colored sugar to emphasize the peppermint.
These bubble bars make lots and lots of bubbles. Make sure to crumble the bar under running water. The more you agitate the water, the more bubbles you get!
