Andrew McCallip wanted to get a batch of red phosphorus to create a room temperature superconductor.
The substance is an ingredient in the preparation of methamphetamine and is controlled by the US Drug Enforcement Agency.
McCallip and his followers on X offered ideas for getting phosphorus.
The discovery of LK-99 could lead to a new era in condensed matter physics.
Experts question the validity of the LK-99 data and are considering alternative explanations for the levitation.
McCallip and his team are working on a superconductor and hope to make a video of levitation.
The results of LK-99 studies cause controversy and doubts about their reliability.
McCallip does not dwell on the results and continues to work on the creation of a superconductor.
