Is it true that you can mix common, household chemicals with a popular carbonated soda to make it glow in the dark?

wood and ashes
The wood in this pile will be reduced to this much ash when it is burned. What happens to the rest of the mass from the wood?

Soap Making

We took the first steps in learning about how soap was once made in the Wood Ashes experiment, using water to dissolve potassium hydroxide out of paper ashes.

If we had been serious about making soap, we would have used a lot more ashes, probably from a wood fire. We would have dissolved the potassium hydroxide in water and then would have boiled the water to concentrate the chemicals.

Wood Ash

This experiment comes from an article I read on technological developments. While reading about ways to make iron, glass, and other historic processes, I became fascinated about the section on soap making. Now, we will not go through the entire process of making soap (at least not this week), but we will experiment with the first steps in classic soap making.

A Cool Change

This time, we are going to look into the sciences of chemistry and energy. It may seem strange to be looking into two different areas of science, but it is not unusual for the areas of science to overlap.
