Questions & Answers

Q: What is a Worthington jet and why is it called a poop splash?

A Worthington jet is the splash of water that occurs when a solid object is dropped into water. It is called a poop splash because it commonly happens with feces in the toilet bowl.

Q: How does surface tension contribute to poop splashes?

Surface tension is the force per unit length on the surface of a liquid. When a solid object is dropped into water, it creates a cavity filled with air. The discontinuity in pressure causes the cavity to collapse, resulting in a splash.

Q: How can you eliminate poop splashes using toilet paper?

By placing a few pieces of toilet paper on the water's surface before defecating, you can vary the surface tension. This prevents the formation of a Worthington jet and eliminates poop splashes.

Q: Why is it important to discuss the science of poop splashes?

The topic affects billions of people worldwide, yet it is rarely discussed in an intelligent and respectful way. By understanding the science behind it, we can find practical solutions to minimize its occurrence.
