![]() ![]() Despite the fact that Bernoulli established the rule, it was Leonhard Euler who developed Bernoulli’s equation in its standard form in 1752. Bernoulli’s Principleīernoulli’s principle, introduced by Daniel Bernoulli, states that as the speed of a flowing fluid (liquid or gas) rises, so does the pressure within the fluid. Fluids have shearing stress that is a million times lower than solids. ![]() Fluids have a critical property: they have extremely little resistance to shear stress when a modest amount of shear stress is applied, their shape changes. Shear stress can alter the geometry of a solid while maintaining its volume. The volume can be changed due to changes in external pressure is rather small in solids or liquids that is solids and liquids are far less compressible than gases. A gas covers the whole capacity of its container, whereas solids and liquids have a fixed volume. Fluid is different from a solid, it does not have its own distinct shape. Every mammalian body constitutes mostly water. Water is not only vital for our survival it is also essential for the survival of every animal species. Earth is surrounded by air, and water covers two-thirds of its surface.

The ball is trying to escape the low-pressure air. If you observe the ball closely as it levitates in the air, you will see that it wobbles in the low-pressure area. When you blow in a fast thin stream (because directs the straw focuses the air to make it thin), the fast air is able to move around the sides of the ball instead of simply pushing it upward from below. ![]() Basically in this simple science project we created an area of low pressure around the ball by blowing into the straw. Once kids have had a chance to experince Bernoulli’s principle first-hand in this EASY floating ball experiment, it’s time to explain they why. If you blow slowly, then the pressure goes back up and the ball falls. NOTE: This only works if you blow hard enough so that there is a steady fast stream of air around the ball. Allow kids time to continue making the ping pong ball float as they experiment with air flow and air pressure to make the ball fly. Put ping pon ball in over the paper cone you created with one hand and in the other blow a constant, staed stream of air to make the ball levitate. Securely tape in place so there are no gaps for air to escape. Insert the smaller part of the bendy straw into the bottom of your paper cone. Pull the two sides of paper around the radius so they overlap and tape into place to make a cone. If you recall from math class, the radius is the straight line from the center of the circle to the outside of the circle. Then students will carefully use scissors to cut out the circle. The technique for this energy experiment is simple, children trace a circle about 6″ in diameter on their piece of colored paper. To try this physics experiment for kids on energy you only need a couple simple materials:
