DESCRIPTION

Exhibit 536 is a spherical glass ampulla mounted on a wood base. Inside there is a glass tube that branches into 5 limbs each of which contains at its end an unidentified mineral fragment of different color: red, gray, iron gray, white and clear gray.

There are two terminals: one for the cathode source of electrons and the other for the anode.

By applying a high voltage between the two terminals, the cathode rays strike the minerals that emit a characteristic fluorescence from which it should be possible to determine their chemical composition.
