Why does balloon experiments work better in dry weather than in damp weather?

Balloon experiments work better in dry weather because low humidity allows for greater static electricity buildup on the balloon's surface. In damp weather, moisture in the air can cause the balloon to lose its charge more quickly, as water molecules can conduct electricity and neutralize the static charge. This results in less effective attraction or repulsion during experiments. Therefore, dry conditions enhance the balloon's ability to demonstrate static electricity effects.
