Can an Umbrella Made of Water Stop the Rain?

Summary by Krater

The creator builds and tests a homemade water umbrella designed to deflect rain using laminar water flow, concluding that while it successfully deflects falling water, scaling it up to cover a person is impractical.

Answers: Can you build a working water umbrella?

• laminar water flow
• fluid dynamics
• momentum
• umbrella engineering
• physics experiments

What it concludes

• A homemade laminar flow water umbrella can successfully deflect small falling water drops and keep a test subject dry underneath.
• Scaling the water umbrella to a larger size creates a battle of momentum where falling rain drops easily break through the water stream.
• Using a high-velocity fire hose creates too much sideways water spray over a 30-foot radius, making it impractical for use as an umbrella.
