We love trying new projects and are always exploring science experiments to see how they work! We also love to add our twist to things, like with this ivory soap experiment. After microwaving the ivory soap, we were able to turn it into fluffy homemade bath paint!! Let me tell you what’s really cool about this. You make this bath paint from soap. So when your children think they are having a blast in the bathtub playing, they are really cleaning the shower for you. That’s a parenting win right there!
What is so cool about this ivory soap experiment?
Ivory soap has a high volume of air whipped into it, so when the soap is heated, it expands rapidly into a huge, fluffy cloud! What’s even better, is the texture after you microwave the ivory soap. It’s fluffy, but firm and mold able so it makes a great activity for sensory play. You can also take the mixture and make your own DIY fluffy homemade bath paint! To really understand the science behind this, head on over to Steve Spangler, as he does a great job at explaining this.
Also, it should be noted that this will only work with Ivory soap. Other soaps don’t have as much air whipped into them and will cause the soap to burn if microwaved long enough.
How to Conduct the Ivory Soap Experiment
First, microwave the ivory soap for about 2 minutes. It will take about 15 seconds before you see the soap begin to expand. Watch as the soap continues to grow at a very rapid rate. Remove from the microwave and let the mixture cool for a minute before touching. Next, play with the mixture, mold it and discuss how the air whipped into the soap, causes it to expand as it does.
How to Make Fluffy Homemade Bath Paint
Find some plastic cups or tubs that you don’t mind making this paint in. Divide the mixture into the different cups.
Add enough water to each cup, that the fluffiness becomes more of a paste. Add a little water at a time and stir. You don’t want to add too much water or the paint won’t be very fluffy. The consistency is completely up to what you prefer. If it’s too fluffy, we have found it makes it hard to make any designs with.
Once you are happy with the consistency, add just a couple drops of food coloring to get your desired color. We used regular food coloring and it did not dye the color of our shower at all. If you are concerned about it dying your shower, you can purchase these bath dyes specifically made for coloring soaps and your own bath paint.
Now you are ready to have some fun and paint! Grad a paint brush and get to decorating the shower! When you are done, it rinses right off, leaving your shower cleaner than it was before.

We hope you guys love this ivory soap experiment and fluffy homemade bath paint as much as we do. Have fun experimenting and don’t forget to check out out our science experiences for more family fun ideas to do at home.
