Nowadays with the advance of technology, small eruptive solar jets became a puzzling curiosity. The impact of solar jets on the solar atmosphere and their interaction with related features of solar activity is discussed. We discovered stable solar sites, ``The Coronal Geysers'', which undergo multiple magnetic field reconfigurations and are the trigger of solar jets. The data analysis and mathematical modelling of these sites and jet phenomena unveiled that heating and kinetic jet emission are triggered by small repeated filament eruptions. These results generated new insights towards understanding the physics of solar eruptions that can potentially impact the near-Earth environment.
