Titanium dioxide is a common additive in many products, including food and cosmetics, due to its brightness and strong adhesion properties. According to the FDA, it's considered a safe substance for general use. However, it is inadvisable to intentionally feed this to your dog or any pets as their bodies may react differently than humans. It's not associated usually with toxicity in dogs, but could potentially cause digestive upset, especially in larger amounts. Keep in mind that pet food and treats do not require coloring or additives for nutritional needs, and natural options are always best. In sum, titanium dioxide isn't notably harmful for dogs but should not be intentionally introduced into their diets.

Electric vehicles (EVs) are vehicles that operate on an electric motor, instead of an internal-combustion engine that generates power by burning a mix of fuel and gases. Therefore, electric vehicles are considered to be zero-emission vehicles, as they emit no exhaust or pollutants from the tailpipe.

There are two main types of electric vehicles: battery electric vehicles and hybrid vehicles. Battery electric vehicles run solely on electricity and need to be recharged on a regular basis, usually at a charging station or with special equipment installed at home. Hybrid vehicles, on the other hand, combine an internal combustion engine with an electric motor, offering more flexibility in terms of range and fuel consumption.

Electric vehicles offer various advantages including cheaper operating costs, lower maintenance costs, and eco-friendliness. However, they also present some challenges like higher initial costs, limited driving range, and longer refueling times compared to traditional vehicles.

Building a vocal booth with PVC pipe is an affordable and customizable way to improve your recording quality. First, calculate the desired size of your booth to determine the amount of PVC pipe and connectors needed. For a standard small booth, assembling a frame using 1-inch PVC pipes into a cube or rectangular shape works well. You will need 90-degree elbow connectors for the corners and T-connectors if you wish to add horizontal supports for stability. After assembling the frame, cover it with dense materials like moving blankets or specially designed acoustic foam to absorb sound. Secure these coverings using zip ties or Velcro strips for easy assembly and adjustment. Remember to leave an open section for the door or use a heavy curtain that can be moved aside. This DIY solution can significantly reduce echo and external noise, offering a cost-effective alternative to professional-grade booths.
