The newly set up aquarium smells like silicone plastic because the silicone used to seal the edges and seams of the aquarium is off-gassing. This is a common occurrence with newly sealed aquariums, as the silicone releases volatile organic compounds (VOCs) as it cures. The smell should dissipate over time as the silicone fully cures and the VOCs are released. It's important to ensure proper ventilation during this process to minimize the smell and any potential impact on the aquarium's inhabitants. **

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. **

Both plastic and glass bottles have their own advantages and disadvantages. Plastic bottles are lightweight, durable, and less likely to break, making them convenient for on-the-go use. However, they can leach chemicals into the contents, are not environmentally friendly, and can retain odors and flavors. On the other hand, glass bottles are non-toxic, environmentally friendly, and do not retain odors or flavors. However, they are heavier, more fragile, and can be more expensive. Ultimately, the choice between plastic and glass bottles depends on personal preferences, intended use, and environmental considerations. **

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. **

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. **

Fireworks rockets are pyrotechnic devices that are propelled into the air and explode to produce colorful and dazzling visual effects. They are typically made of a cylindrical tube filled with explosive materials and a fuse at the base. When the fuse is ignited, the rocket is propelled into the sky and bursts into a display of bright lights, sparks, and loud noises. Fireworks rockets are commonly used in celebrations and events to create a spectacular and memorable experience for spectators. **
