They arent bringing anything on ebay.
they are made from plastic because plastic doent dent and is light weight
ok thanks
To make a simple microscope out of a plastic bottle, you will need to cut off the bottom of the bottle and place a small drop of water on the flat surface created. Then, take a clear piece of plastic or glass and place it over the water droplet to magnify the image. Lastly, hold the bottle up to a light source to illuminate the object you want to view.
It floats because the water is heaver then the bottle. The bottle is light so it floats. No,It floats because the particles are free to move inside but with water in it there is not enough space for the particles to move so it floats.
You can keep milk in a plastic drinks bottle in the fridge, but it's best to use the original container if possible. Milk is sensitive to light and air, which can accelerate spoilage; the original opaque cartons are designed to protect it from these factors. If you transfer it to a clean, opaque plastic bottle, it should last as long as it would in its original packaging, provided it's kept sealed and refrigerated.
All of the colors in the white, except the green, are absorbed by the plastic. The green is the only light that survives the trip all the way through and comes out the other side. This is the main reason the object is known as "a green bottle".
The best safety features to look for in cycle helmets include impact-absorbing foam, a secure fit system, and MIPS technology for added protection against rotational forces. When it comes to lights, look for helmets with built-in LED lights for increased visibility in low-light conditions.
These quality helmets are made in the country of Korea. They are made from composite resins and are precision made. They are extremely durable and light.
Plastic is most of the time light to carry by itself, unless there is something in the plastic.
To make a liter of light, you can use a simple setup involving a clear plastic bottle filled with water mixed with a small amount of bleach or a similar transparent liquid. Place the bottle in direct sunlight, and the sunlight will refract through the water, creating a bright, illuminated effect. This method can effectively mimic a light source and can be used as a creative lighting solution in areas where electric light is not available.
No, plastic does not absorb light. Instead, it reflects and transmits light, which is why plastic is often used for things like windows or packaging to allow light to pass through.
Not all plastic materials are transparent because some plastics are formulated to be opaque or colored. The opacity is often due to the presence of additives, fillers, or pigments that block light from passing through the material. Additionally, the molecular structure of the plastic can affect its transparency.
