You're about to experience a new, available and exciting technology that's going to make us rethink how we waterproof our lives. What I have here is a cinder block that we've coated half with a nanotechnology spray that can... Read More

Key Insights

• 🔬 Nanotechnology spray called Ultra-Ever Dry turns any material into a superhydrophobic shield, repelling water and other water-based materials.
• 💧 The more round a water droplet is on a surface, the more hydrophobic it is; an angle over 150 degrees is considered superhydrophobic.
• 🧤 One glove coated with the nanotechnology spray repels water, while the other remains wet, showcasing the effectiveness of the coating.
• 🌐 Nanotechnology allows for the control and manipulation of atoms and molecules, bringing significant benefits.
• 🌍 The nanotechnology coating works not just with water but also with concrete, water-based paint, mud, and refined oils.
• 🙌 The nanotechnology coating creates a rough and craggly surface with billions of interstitial spaces filled with air, making it resistant to water and allowing it to slide off.
• 💡 The applications of this nanotechnology coating are vast, including anti-wetting, anti-icing, anti-corrosion, anti-bacterial, and self-cleaning properties.
• 🌟 Nanotechnology has the potential to revolutionize various industries and fields of work.

Questions & Answers

Q: What is Ultra-Ever Dry and how does it work?

Ultra-Ever Dry is a nanotechnology spray that can be applied to almost any material to make it superhydrophobic. It forms a rough and craggly surface filled with nanoparticles and air molecules that create a layer of air, which repels water and other fluids.

Q: How is the superhydrophobic property of a surface measured?

The superhydrophobic property of a surface is measured by observing the roundness of a water droplet on that surface. The rounder the droplet, the more hydrophobic the surface is. A freshly waxed car has water droplets with a slump of about 90 degrees, while a windshield coating gives around 110 degrees. The nanotechnology coating featured in the video showcases water droplets with a range of 160 to 175 degrees, which is considered superhydrophobic.

Q: What are some examples of materials that can be made superhydrophobic using Ultra-Ever Dry?

Ultra-Ever Dry can be applied to various materials including concrete, water-based paint, mud, and even some refined oils. These materials can acquire the superhydrophobic property, repelling water and other liquid-based substances.

Q: What are the potential applications of nanotechnology and superhydrophobic coatings?

The potential applications of nanotechnology and superhydrophobic coatings are extensive. They can be used for anti-wetting purposes, preventing ice formation (anti-icing), preventing corrosion, inhibiting bacterial growth (anti-bacterial), and creating self-cleaning surfaces. These properties could revolutionize various fields of work by providing innovative solutions to common problems.
