    a normal balloon is neutral charge

    When you rub a balloon against your hair. The electron charges on your head move to the balloon and the balloon gets a NEGATIVE CHARGE.

    If you rub the balloon against the same or similar material and the balloon gets the same type of charge.

    then the balloons will each repell each other. because like charges repell

    unlike charges atract.

    A POSITIVE charged item will atract a neutral item

    or a negative item

    a negative item will atract a neutral item or a positive item.

    That is why balloons repel each other.

    Here is a fun one to try.. rub the balloon against your head and then touch it to the wall..

    It will stick to the wall and eventually wiggle down

    your hair may stand on end too.

    When they rub up against stuff, they tend to collect spare electrons (negative charge), which is why they attract the hairs you rub them on (the hairs are now positively charged). The balloons will repel each other because they both carry a negative charge.

    Yes they can. If both balloons have the same charge (positive or negative) they will repel each other like magnets.
