A Simple Floating Ball Pipe Demonstrating the Bernoulli Effect and the Coanda Effect

Short Explanation of the Physics Concepts:

• Bernoulli's Principle: This principle states that an increase in the speed of a fluid (in this case, air) leads to a decrease in pressure. As air flows around the ball, it speeds up, creating a low-pressure zone that helps keep the ball centered in the airflow.
• Coanda Effect: This effect describes the tendency of a fluid jet to stay attached to a convex surface. As the ball begins to move out of the jet, the airflow adheres to its surface, pulling it back into the center of the stream.

Both principles are fundamental in understanding how airplanes generate lift.

Design Details:
The pipe is printed in two parts to minimize the need for support material. The two parts can be easily assembled by pushing the top part into the designated hole.

While I attempted to print a ball for the demonstration, I found that a ping-pong ball worked much better due to its lighter weight, effectively showcasing the effect.
