Its scalar energy. I have a scalar wand and its super - never have to charge it or anything . Those tin cans have a 1 year expiry date writen on them.

Thank you for the explanation of the type of energy the cans purport to use. When I went to look up scalar one of the first things that came up was this 2021 medical research article below. I suppose in some future hopes of banning the trendy disc necklaces for emitting radiation. That's always a red flag to me that there must be something helpful to mankind about it or why bother. I've been suspicious lately that we've had a number played on us regarding the healing properties of radon. People used to bathe in the radon waters at the various naturally occurring springs found throughout the US. They actually called it "Taking The Cure".
All these old near abandoned towns with "spring" following the name, if one looks up the history and images there was usually a grand bathhouse that is no longer standing. Look only to Hot Springs, AR that actually preserved many of them. Originally the baths were hawked as Radon Water.
