Experiment four utilized a mixture that was approximately 7.5% sodium alginate by weight. While it generated a jelly layer that would be suitable for most, I believe that we can do better.
Calcium content in water will impact the effectiveness of the jelly bombs (and many other bath products). I have what I would classify as slightly hard water. Given this, I realize that my results are better than many will see (and worse than others). With this in mind, I want a jelly bomb that will tolerate a wide range of water conditions.
Experiment 4 Ingredients:
- Baking Soda – 150 grams
- Citric Acid – 100 grams
- Sodium Alginate – 20 grams
- Binder: 91% Isopropyl Alcohol
The jelly bombs themselves are cheap and easy to make with ingredients that you can quickly get through amazon or even local grocery or health food stores. In truth, as a whole these jelly bath bombs unmolded better than any other bath bombs I have ever made – I typically didn’t have any that failed to hold their shape or tried to crumble on me.
For most, I am making the mini-bombs as a proof of concept test model. I did this primarily so that I did not have to waste as much water to get a sound test.
