Extending a downspout made of PVC involves several steps and requires specific tools and materials. Firstly, ensure you have the correct size PVC pipe that matches your existing downspout. Measure the length needed for the extension, keeping in mind the overall slope and flow direction. Cut the PVC pipe using a hacksaw or PVC cutter, ensuring a clean, smooth cut. Apply PVC primer to both the end of the new piece and the inside of the existing downspout. Then, use solvent cement to join them, aligning the pieces carefully. For added stability, especially on longer extensions, install support brackets every 6 to 8 feet. Lastly, seal any joints with silicone caulk to prevent leaks. This method ensures a secure and functional extension.

Polyethylene glycol (PEG) is a common ingredient in various medications, serving as a solvent, excipient, or base. Its most familiar use is in laxatives, like MiraLAX, where it acts by retaining water in the stool, increasing stool volume, and triggering bowel movements. Additionally, PEG is a component of some bowel preparation products used before colonoscopy procedures, such as GoLYTELY. Beyond its laxative role, PEG can be found in various pharmaceutical formulations, including certain tablets and capsules as a binder, in ointments as a base, and even in injectable medications as a solubility enhancer or to prolong the medication's duration in the body. Its versatility and low toxicity make it invaluable in medication development and formulation.

Industrial inkjet printers operate through a non-contact printing technology, enabling them to print on various substrates. They use piezoelectric or thermal printheads to generate tiny droplets of ink. In piezoelectric inkjet printers, electric charges are applied to piezoelectric crystals, causing them to change shape and eject ink from the nozzle. On the other hand, thermal inkjet printers heat the ink to create a bubble that expands and forces ink out of the nozzle. Once the droplets are expelled, they are directed onto the printing surface by the printhead moving across the media or by the media moving beneath the printhead. This flexibility allows for high-speed printing on different types of materials, including paper, plastics, textiles, and metals, making industrial inkjet printers versatile tools for various applications, from packaging to signage and decoration.
