Magnetic and Material Properties Assessment

Zach Kaplan and Keith Schacht present six innovative materials and technologies with unexpected properties. They explore applications for a soft magnet from GelTech, a magnetically-levitating board, a 10-foot pole that fits in a pocket, a dry liquid from 3M, shape-retaining plastic, conductive ink, and odor-detecting packaging. The presentation emphasizes the importance of understanding unexpected properties and their potential applications, highlighting collaborations and creative concepts for future products.

What is the unique property of the gel magnet discussed in the first section?

• It is a liquid magnet.

• It is a soft yet strong magnet.

• It changes color when heated.

• It is a transparent magnet.

How did Roman Coppola's approach to presenting the gel magnet concept differ from Zach and Keith's?

• He presented it as a current product for sale.

• He used a live demonstration.

• He used a scientific report.

• He created a documentary.

What is the purpose of the magnetic braking system in the magnetically-levitating board concept?

• To change the direction of the board.

• To increase the speed of the board.

• To stop the board at the end of the slide.

• To make the board float.

What unexpected property occurs when a magnet is dropped down an aluminum tube?

• The magnet becomes non-magnetic.

• The magnet changes color.

• The magnet speeds up.

• The magnet falls slowly.

What is a potential use for the 10-foot pole discussed in the fourth section?

• As a garden tool.

• As a musical instrument.

• As a portable soccer goal.

• As a fishing rod.

What is the main advantage of the dry liquid developed by 3M?

• It is highly flammable.

• It is non-conductive and evaporates quickly.

• It is sticky and colorful.

• It is a strong adhesive.

What is the 'shape-retaining property' of the plastic developed by Sekisui Chemical?

• It changes color when stretched.

• It melts at high temperatures.

• It retains its shape after being bent.

• It bounces back to its original shape.

How can conductive ink change the way we interact with paper?

• By allowing paper to detect bending.

• By making paper waterproof.

• By making paper glow in the dark.

• By making paper edible.

What is a potential application of the odor-detecting dyes developed by Professor Suslick?

• Detecting water levels.

• Detecting spoiled food.

• Detecting sound waves.

• Detecting light intensity.

What was the unexpected observation made by Steve Jurvetson's son with the hydrophobic sand?

• It dissolved in water.

• It remained dry after being submerged.

• It floated on water.

• It changed color in water.
