Driving Nonspontaneous Processes
In this video Paul Andersen explains how you can drive non spontaneous processes by adding external energy (like electricity or light) or by coupling it to a spontaneous process (like the conversion of ATP to ADP)

TED-Ed: Valentin Hammoudi: How tall can a tree grow?
Reaching heights of over 100 meters, Californian sequoias tower over Earth's other 60,000 tree species. But even these behemoths seem to have their limits: no sequoia on record has been able to grow taller than 130 meters. So what...
