Demonstration – Bernoulli’s Principle

Take two empty soda cans and lay them on their side about 4inches apart on a flat surface such as a lab table.  Get level with the lab table and blow between the cans.  The cans move together not apart.  The faster moving fluid between the cans have a lower pressure, as indicated by Bernoulli’s Principle, than the air on the outside of the cans.  The air at a higher pressure will move to the area of lower pressure and the cans which are in the way will be pushed together during the process.
