I wonder what the precision of the can's manufacture really is?  Did they leave the pull tabs on?  Were they completely dry?

What I am getting at is how replicable this might be...does one need to use cans all made the "same" from a single drink company?  Can (no pun intended) they be mixed?

Interesting that it is just below A 440Hz.

Thanks for pointing out this really cool development.

Wilby,
Amazing stuff,

Acoustic actuators harness sound waves to physically move objects, and Lerosey points out that the acoustic field generated by the cans is not only more precise than an ordinarily focused field, it is also stronger

They organize and play the "fields" like an instrument!! This guy could "Create" some wild effects with this...............

Thanks
