Calculation for this is based on Bernoulli's principle. If you hang two ping pong ( table tenis )
balls from a fixed support by strings and let them be side by side at a distance of approximately 4 cm from each other and blow air , with the help of a drinking straw, in the space between them then the two balls will come towards each other and stick together. This happens because the air ...
