What Links Toothpaste, Ketchup, and Silly Putty? Quiz Answers 2026

What links toothpaste, tomato ketchup, and silly putty? They are all examples of non-Newtonian fluids, substances that don't follow Newton's law of viscosity. This fascinating connection was just one of the brain-teasers in a recent Saturday quiz that also covered politics, history, and pop culture. In this article, we'll explore the science behind these everyday items, dive into other intriguing quiz questions, and provide answers to satisfy your curiosity.

The Science Behind Non-Newtonian Fluids

Non-Newtonian fluids are everywhere, from your kitchen to your toy box. Unlike water, which flows consistently regardless of force, these fluids change their viscosity under stress. Toothpaste stays on your brush until you squeeze the tube, then it flows. Tomato ketchup is thick in the bottle but becomes runnier when shaken. Silly Putty bounces like a solid when thrown but stretches like a liquid when pulled slowly.

Examples and Behaviors

Here's a quick comparison of how these fluids respond to different forces:

Understanding these properties helps scientists and engineers design better products, from ketchup bottles that don't clog to paints that apply smoothly.

Other Highlights from the Saturday Quiz

The quiz also tested knowledge on a variety of topics. Here are some key takeaways:

• Zohran Mamdani, NYC mayor, used to rap as Mr. Cardamom.
