  Boiling crisis experiments are carried out in the vicinity of the liquid-gas
critical point of H2. A magnetic gravity compensation setup is used to enable
nucleate boiling at near critical pressure. The measurements of the critical
heat flux that defines the threshold for the boiling crisis are carried out as
a function of the distance from the critical point. The obtained power law
behavior and the boiling crisis dynamics agree with the predictions of the
vapor recoil mechanism and disagree with the classical vapor column mechanism.
