An experiment is described which attempts to replicate the results of Podkletnov et al. concerning an alleged detection of a gravity-like force above a spinning superconductor. The experiment is based on Podkletnov’s published descriptions plus personal communications but found no evidence of a gravity-like force to the limits of the apparatus sensitivity. A full description of the apparatus and operation is given.

In our case, values of the inexplicable weight changes, which are well reproducible from sample to sample, are about 0.01 wt. %.

Although the payoff of the discovery of a superconductor-mediated interaction between matter and gravity would be tremendous, only a few researchers are pursuing this goal. The main reason for this is the adherence to dogma concerning the impossibility of increasing the matter/electromagnetic coupling coefficients. This adherence is reinforced by reputable physicists pointing out that the theoretical constructs presented so far are based on questionable foundations. As with any forays into the unknown, one has to accept a few bumps along the way, including sometimes going back to the starting point in order to start again. The likelihood of scientific ridicule is extremely high in the search for laboratory-scale gravitational interactions.
