Polyethylene glycol (PEG) is a chemical compound that can be found in a wide range of products, from pharmaceuticals to personal care items. In the context of vaping, PEG, along with propylene glycol (PG), and vegetable glycerin (VG), are commonly used as base carriers for the nicotine and flavoring agents in e-liquids. PEG's role is to help produce the aerosol that is inhaled by the user, replicating the sensation of smoking. Its use in vape juices, however, is somewhat less common compared to PG and VG, which are more popular due to their ability to better balance flavor delivery and vapor production. While generally considered safe for inhalation in the concentrations found in vapejuices, there continues to be ongoing research into the long-term effects of inhaling vaporized substances, including those containing PEG. For individuals concerned about the contents of their vape juice, checking the ingredient list or contacting the manufacturer directly can provide specific information about whether PEG is present.

To build an Ink Cookie you're likely referring to a themed cookie inspired by something like the game Cookie Run or a creatively decorated cookie using edible ink. Begin by preparing your favorite sugar cookie dough, roll it out, and use a cookie cutter for shapes. After baking and cooling, the real art begins with decorating. Use royal icing as a base coat on your cookies. Once the base coat is dry, sketch your design with an edible ink marker. For detailed artwork, edible ink and a fine brush or a food-grade printing technique are options. Pay attention to the consistency of the icing for finer details. Creativity is key, so let your imagination run wild with designs, colors, and patterns. Remember, the inks should be food-grade to ensure they are safe for consumption.

Doing powder coating at home involves applying a powder material, typically a thermoplastic or thermoset polymer, to a surface, and then curing it under heat to create a hard finish, often used for metals. It requires specific equipment: a powder coating gun, powders, an electric oven (not used for food), and safety gear, including a respirator and goggles. The process includes cleaning the item thoroughly, applying the powder with the gun, and then curing it in the oven according to the powder's specifications. While it's a durable and attractive finish, it's essential to follow safety procedures due to the toxic nature of the materials when heated, and to ensure compatibility with your home's electrical supply, especially the oven's requirements. It's also worth practicing on less important pieces before moving onto more critical projects to perfect your technique.
