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.
