In Minecraft, an ink sac is a primary dye that is mainly obtained by killing squids, which spawn in water. To "turn" or utilize an ink sac, you have several options. Firstly, it can be used as a black dye to change the color of wool, beds, or other dyeable objects. To dye an object, simply place the item and ink sac together in your crafting table or inventory crafting grid. Secondly, ink sacs can be used to craft a book and quill, which requires an ink sac, a book, and a feather, allowing you to write inside them. Lastly, they are used to create dark prismarine blocks by combining them with prismarine shards. Despite its mundane appearance, the ink sac is versatile in crafting and decoration within the game.

Epoxy resins, including the popular 30-minute variety, do not significantly expand in the traditional sense like some foaming adhesives or polyurethane-based products. When epoxy is mixed, the two components - resin and hardener - react chemically, resulting in a hard, durable bond. The slight expansion some users might observe is mainly due to the presence of air bubbles getting trapped during the mixing process, not the epoxy itself expanding. To minimize any such issues, thorough mixing to achieve a uniform consistency, followed by careful application, is recommended. However, for tasks requiring gap filling, consider using a filler product or selecting a specifically formulated epoxy putty.

When painting PVC pipe, choosing the right type of paint is crucial for durability and appearance. Latex-based paints are highly recommended due to their flexibility, which can accommodate the slight expansion and contraction of PVC materials. Before painting, it's important to prepare the PVC surface adequately to ensure proper paint adhesion. Sanding the pipe lightly with fine-grit sandpaper and cleaning it with a solvent like isopropyl alcohol can create a better surface for the paint. Additionally, applying a primer designed for plastic surfaces can significantly improve paint adherence and longevity. Avoid using oil-based paints as they can become brittle and crack over time when applied to PVC.
