Yes, the soft, elastic silicone phone cases can come from the silicone tube. The silicone tube contains liquid silicone material that can be molded and shaped into various products, including phone cases. The liquid silicone is poured into molds and then cured to create the soft and elastic phone cases. Therefore, the silicone tube is the source of the material used to make the phone cases. **

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. **

Photography can be a valuable component of an interior design portfolio, as it allows students to showcase their ability to capture and present their design work. However, a comprehensive interior design portfolio should also include hand-drawn sketches, technical drawings, mood boards, and other visual representations of design concepts. These additional elements demonstrate a student's creativity, technical skills, and design process, which are important aspects of studying interior design. Therefore, while photography is important, it should be supplemented with a variety of other visual materials to create a well-rounded portfolio for studying interior design. **

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. **

Soft fabric for softboxes in photography can be purchased at specialty photography stores, online photography equipment retailers, or craft stores that carry fabric suitable for light diffusion. Many online marketplaces like Amazon or B&H Photo Video offer a variety of softbox fabric options in different sizes and materials. It's important to choose a fabric that is heat-resistant and designed for light diffusion to ensure optimal results in photography lighting setups. **

Yes, you can apply new silicone on top of existing silicone as long as the old silicone is clean, dry, and in good condition. It is important to remove any dirt, dust, or residue from the old silicone before applying the new layer to ensure proper adhesion. Additionally, make sure to use a compatible silicone product to avoid any compatibility issues. **
