Summary:
- Researchers have developed a new technique to levitate multiple objects using sound waves. This is an important advancement in the field of acoustic levitation, which has applications in materials science, chemistry, and even medicine.
- The key challenge they overcame is the "acoustic collapse" phenomenon, where the sound waves interfere with each other and cause the objects to fall. By carefully controlling the sound waves, the researchers were able to stably levitate up to three objects simultaneously.
- This breakthrough opens up new possibilities for manipulating and studying materials in a contactless environment, which could lead to important discoveries and innovations in various scientific disciplines.
