Question

explain why when we blow air in the spaces between two inflated balloons and hanging about 10cm apart on a stick , the two balloons come closer​

Answer 1

After blowing the air between the balloons pressure of air between them decreases. Due to the difference of the pressure there is net force on the balloons, so they come closer. because when we blow then there is less amount of air to fill that place balloons come towards each other.
