Скачать или смотреть The 5-Cent Secret Inside Your Showerhead 🚿

Ever wonder how your shower feels like it has high pressure, even while it's saving water? The secret is a tiny, 5-cent part called a *shower flow restrictor**. We explain **how flow restrictors work* and how they use science to *increase shower pressure* perception.

In this video, we dive into the hidden mechanism inside your showerhead. In the US, showers are often limited to $2.5$ gallons per minute (GPM), and in the EU, regulations like $9$ liters per minute are common. This isn't a flaw; it's by design.

Learn how this tiny plastic disc creates a "choke point," forcing the same amount of water through a much smaller opening. We'll explain the simple fluid dynamics—the **Venturi effect**—that this tiny part uses. By increasing the water's *velocity*, it makes the stream feel stronger and more satisfying, all while saving you water and money. It's a tiny piece of genius engineering in your bathroom.

This is how the tiny, 5-cent part in your shower works.
