How to Make Soap Out of Guava Leaf Extract for a Science Investigatory Project
In our personal experience, the hardest part about a science investigatory project is simply coming up with a good idea. And we suggest that for your investigatory project you find a topic that's both novel and useful.
Check out this science tutorial to learn how to make a bar of soap out of guava leaf extract, which was made by Dragonknight15 and fellow peers for their 3rd year chemistry class. This guava-infused soap actually helps clear up acne. You'll need sodium hydroxide, guava leaves, containers, and lavender scent.
