To determine which of the following is not a characteristic of a thunderstorm, we will analyze each option provided:

1. **Spark of light in the atmosphere**: This refers to lightning, which is a common occurrence during thunderstorms. Therefore, this is a characteristic of thunderstorms.

2. **Rapidly rotating winds**: While thunderstorms can have strong winds, they do not typically feature rapidly rotating winds. This characteristic is more associated with tornadoes or cyclones. Thus, this option is likely the correct answer.

3. **Loud noise**: The loud noise associated with thunderstorms is known as thunder, which is produced by the rapid expansion of air heated by lightning. This is indeed a characteristic of thunderstorms.

4. **Heavy rains or hail**: Thunderstorms are known for producing heavy rainfall and sometimes hail. This is a typical characteristic of thunderstorms.

Based on the analysis, the option that is not a characteristic of a thunderstorm is:

**Answer: 2. Rapidly rotating winds**
