The exposure of YBCO to an air atmosphere at first at pH2O = 110 Pa and then\nat pH2O = 1 kPa has been used for uncharacteristic and unusual properties of\nYBCO to be observed. Among them there was an increased reactivity of YBCO with\nrespect to water. Besides, it was experimentally obtained extremely excessive\nweight gain of hydrated YBCO samples that was not corresponding to the quantity\nof the absorbed water. Finally, we obtained the significant negative value of\nthe room-temperature (RT) magnetic susceptibility in conventional magnetic\nstudy of the hydrated YBCO that was confirmed by the direct observation of\ndecreasing weight of the same samples that were suspended above the source of\ncontrolled magnetic field (DC mode) at RT. All the results were explained on\nthe basis of an approximate idea that there is a certain source of attractive\nforce inside YBCO, acting on surrounding particles and bodies.\n
