Brooke has an aluminum can. The electrical charges move easily through it, so it is a(n)  __________________.

• conductor

• insulator

• static discharge

• electric force

Ben has a rubber balloon. The electrical charges do not move easily through the balloon, so it is a(n) ____________________.
