What Are Materials with Unexpected Properties?

TL;DR

Materials with unexpected properties can revolutionize various applications, such as a soft magnet capable of functioning effectively or a 10-foot pole that easily fits in a pocket. These innovations, including shape-detecting ink and odor-sensing dyes, challenge our assumptions and can lead to new technologies that enhance everyday experiences, improve safety, and change our interactions with products.

Transcript

Zach Kaplan: Keith and I lead a research team. We investigate materials and technologies that have unexpected properties. Over the last three years, we found over 200 of these things, and so we looked back into our library and selected six we thought would be most surprising for TED. Of these six, the first one that we're going to talk about is in ... Read More

Key Insights

• 🧲Unexpected properties change our understanding: The gel magnet showcased in the content surprised viewers by being both soft and a strong magnet. This challenges the assumption that magnets have to be hard and changes our understanding of how magnets can work.
• 🧲Thinking about applications reveals possibilities: Thinking about how the gel magnet could be applied in the world, such as using it on cabinet doors or on the bottom of sneakers, helps us understand the potential and possibilities of the material.
• 🎥Presentation style matters: The way ideas are presented can make a big difference in how they are received. The example of presenting the gel magnet concept as if it was already for sale made it more powerful and allowed people to imagine the experience in detail.
• 📦Collaboration and creativity can lead to powerful ideas: Collaborating with filmmaker Roman Coppola and his team resulted in a powerful commercial that showcased the potential of the gel magnet. Their different approach to presenting the concept made it even more impactful.
• ♂️New technologies can revolutionize experiences: The concept of a magnetically-levitating board for water slides, using a gel magnet lining and magnetic braking system, could provide a thrilling experience for adventurous individuals.
• 🔧Unexpected properties can have practical applications: The 10-foot pole that can fit in a pocket has a wide range of practical applications, such as serving as an antenna, a soccer goal, or a tool for cleaning ceiling fans or spider webs.
• 💧Dry liquid has unique properties: The dry liquid developed by 3M evaporates rapidly, making it feel cold and safe for use. It has various applications, including use in water guns, fire suppression, and cooling down basketball players during a game.
• 📚Ink with shape-detecting properties can change interactions: Ink that changes resistance based on paper bending can revolutionize interactions with printed materials, allowing for applications like determining the page number of a book or detecting bending in games and business cards.
• 👃 Detecting smells through color changes: The matrix of color dyes developed by Professor Ken Suslick and Neil Rakow can detect various odors, making it useful for detecting spoiled food, fire safety, and medical diagnoses. This technology could improve safety and diagnostics in various fields.

Questions & Answers

Q: How do unexpected properties challenge our understanding of the world?

Unexpected properties in materials and technologies can lead to a shift in our understanding of how things work. For example, the soft magnet challenges the assumption that magnets must be hard, changing our perception of magnetism entirely.

Q: What are some potential applications for the gel magnet?

One potential application for the gel magnet is lining cabinet doors to reduce noise and allow for easier closing. Another application is sticking the gel material to the bottom of sneakers, allowing people to hang their shoes on metal sheets instead of using shelves.

Q: How can the 10-foot pole be used in different scenarios?

The 10-foot pole, which can be easily rolled up and fit in a pocket, has various applications. It can act as a concealed antenna for soldiers, a collapsible soccer goal, or a cleaning tool for hard-to-reach places.

Q: How can ink that detects bending be used?

By applying the ink to a book, the book itself can detect what page the reader is on based on the curvature of the pages. Additionally, the ink can be used in various printed materials, such as business cards or board games, changing the way users interact with them.

Q: How does the dry liquid used in the water guns work?

The dry liquid developed by 3M evaporates 25 times faster than water, creating a cooling effect when sprayed. It can be safely sprayed on individuals without getting them wet, as it is non-conductive and won't cause any damage to electronics or other materials.

Q: What are the potential uses of the shape-retaining plastic?

Shape-retaining plastic opens up possibilities for creating products such as watches without buckles or picnic sheets that wrap around tables to prevent them from blowing away. Its ability to hold its shape can also be useful in various other applications, such as automotive or furniture design.

Q: How does the scent-detecting ink work?

The scent-detecting ink contains a matrix of color dyes that change color in response to different odors. By formulating specific dyes to detect specific odors, the ink can be used in various applications, such as detecting spoiled food or even diagnosing diseases in medical settings.

Summary & Key Takeaways

• Researchers Zach Kaplan and Keith Schacht discuss their exploration of materials and technologies with unexpected properties.

• They showcase six examples, including a soft magnet, a 10-foot pole that fits in your pocket, and ink that can detect bending.

• Each example presents unique applications, such as using the soft magnet on cabinet doors or creating a shape-retaining picnic sheet.
