The black mini-mold spot under the silicone strip in the shower is likely a small patch of mold or mildew. Mold and mildew thrive in damp, warm environments, making the shower an ideal location for their growth. The silicone strip provides a perfect surface for mold to grow on, especially if it is not regularly cleaned and dried. It is important to address this issue promptly to prevent further mold growth and to maintain a clean and healthy shower environment. **

Yes, silicone can be used outdoors in sub-zero temperatures. Silicone is known for its ability to withstand a wide range of temperatures, including extreme cold. It remains flexible and retains its properties even in sub-zero conditions, making it suitable for outdoor applications in cold climates. However, it's important to note that the specific type and formulation of silicone should be chosen based on the intended use and the expected temperature range. **

Yes, silicone does stick to silicone. When two silicone surfaces come into contact, they tend to adhere to each other due to their similar chemical composition. This property makes silicone a popular material for creating airtight seals and bonding silicone-based products together. **

It is generally not recommended to apply new silicone on top of existing silicone. The new silicone may not adhere properly to the old silicone, leading to potential issues with adhesion and durability. It is best to remove the old silicone completely before applying a new layer to ensure a proper bond and a long-lasting seal. **

Yes, silicone can be applied on top of existing silicone. However, it is important to ensure that the existing silicone is clean and free of any dirt, dust, or residue before applying new silicone. Additionally, it is recommended to use a silicone primer to promote adhesion between the old and new silicone layers. This will help to create a strong bond and ensure a durable seal. **

Jogging in one spot can be an effective form of cardiovascular exercise, especially if done at a high intensity. It can help improve cardiovascular fitness, burn calories, and strengthen leg muscles. However, it may not be as effective as traditional jogging or running outdoors in terms of engaging different muscle groups and providing a change in scenery. It can still be a convenient option for those with limited space or time. **

Silicone lenses are a type of contact lens made with a silicone-based material, which allows for increased oxygen permeability to the eye. This can help reduce the risk of eye infections and improve overall comfort. Silicone hydrogel lenses are a specific type of silicone lens that also includes hydrogel, a water-absorbing material that helps keep the lenses moist and comfortable for longer periods of time. These lenses are popular for their breathability and comfort, making them a popular choice for contact lens wearers. **

Exercise has been shown to have a positive impact on cognitive function and overall brain health. Regular physical activity can improve memory, attention, and decision-making skills, leading to better cognitive performance. Additionally, exercise has been linked to the release of chemicals in the brain that promote the growth of new brain cells and improve overall brain function. Therefore, it can be said that exercise makes you smarter rather than dumb. **
