Observe the behavior of alpha rays to learn what they are.

- By utilizing the temperature gradient generated in the container by the dry ice, you can make the ethanol vapor become supersaturated. In the vapor, you will see flight paths.
- The radium ball included in this kit is a weak radiation source. It has been solidified for safety to prevent naturally radioactive, rare mineral elements from dispersing.

*The radium ball is a very weak radiation source. It has no effect on the human body.
