Like the beads of carbon dioxide in water that has been warmed, through the strong influence of heat the residual substances shrivel up after the separation and precipitation of the higher quality constituents[11]. Due to the high pressure the outer envelope or the carrier-substance will be crushed and in this way the de-energised elements released.

In the second case, a marriage takes place between the residual substances. In short, the inferior product of synthesis that science calls synthetic petrol (gasoline) is produced. The moment this second, inferior synthesising process happens, a pressure recoil (cavitation) takes place due to the emission or discharge of the higher constituents (viz. the pressure reflux in high-pressure boilers).
