Fluid Dynamics and Material Properties

In the BYU Splash Lab, Professor Tad Truscott demonstrates fluid dynamics using high-speed cameras, eggs, and lasers. The lab explores how eggs spin and create milk jets, analyzes droplets on hydrophobic surfaces, and uses lasers to study fluid movement. Experiments include observing marshmallows with liquid nitrogen and creating daffodil dust. The video emphasizes the importance of breaking eggs and burning Peeps for research.

What is the maximum frame rate of the photron camera used in the BYU Splash Lab?

• 500,000 frames per second

• 2 million frames per second

• 750,000 frames per second

• 1 million frames per second

Why does a raw egg wobble when spun?

• Because it is heavier than a hard-boiled egg

• Due to air pockets inside the egg

• Because it has a thicker shell

• Due to the liquid inside moving back-and-forth

What force is responsible for creating fluid jets when an egg spins in milk?

• Centripetal force

• Magnetic force

• Gravitational force

• Centrifugal force

What type of surface repels water and allows beads to form?

• Conductive surface

• Absorbent surface

• Hydrophilic surface

• Hydrophobic surface

What is a potential application of super hydrophobic surfaces?

• Increasing friction

• Improving thermal conductivity

• Creating self-cleaning surfaces

• Enhancing electrical insulation

What is the primary purpose of using lasers in the Splash Lab experiments?

• To create holographic images
