Apply Heat to Shrink Tubing

What happens here

Acquire a heat source; the narrator uses a small torch, but a heat gun is a safer and more controlled alternative. Begin to apply heat evenly around the heat shrink tubing, moving the flame or heat gun constantly to prevent scorching. As the tubing heats, it will begin to shrink and conform to the shape of the cable and connector. Continue heating until the tubing is tight and secure. You will notice a small amount of adhesive oozing out from the ends of the tubing, indicating a strong, waterproof seal. Ensure the tubing has completely shrunk and formed a solid, reinforced layer over the vulnerable area.

Goal: Use a heat source, such as a torch or heat gun, to evenly heat the tubing until it shrinks tightly around the cable and connector, securing it in place.
