If it will work with H2O then I can be certain it was not Tritium that was produced with D2O.
With H2O it could be UDH what would be great. And also the experiment would be significantly cheaper and affordable to anyone.
What is required is to replicate it by as many people as possible and reveal all findings. It is necessary to exclude any possible errors by finding nature of the experiment.
But without more people it will take at least months.
