This video from an experiment at the Argonne National Laboratory sheds light on the phenomenon of using acoustics to help drops of liquid levitate - something that could very well make it to a fine dining table near you.
Basically, scientists used a combination of liquids and pharmaceuticals to produce a soluble solution that can be suspended between two speakers facing each other. The research involved using an acoustic levitator, equipment that is commonly used by NASA for microgravity stimulations.
Staff shortages are hitting the hospitality sector hard, prompting some restaurants to look outside the industry to train those without restaurant experience for life in the kitchen. Andrew Friedman finds out more.
