Some air is blown gently in the space between the balloon in horizontal direction. Explain what happens to the balloons.
Answer
The two balloons move towards each other. On blowing air between the balloons, the speed of air increases and pressure reduces. The high atmospheric pressure on the sides pushes the balloons towards each other.
