There may be several reasons for this issue. It could be due to a clogged feed or nib, improper ink flow adjustment, or a damaged nib. Try cleaning the pen thoroughly, adjusting the ink flow if possible, or replacing the nib if necessary. If the problem persists, consider seeking professional help from a pen specialist.

A spring in a stapler provides the force needed to push the staples forward and into the paper. When the stapler is pressed down, the spring compresses, storing potential energy. When the pressure is released, the spring expands, driving the staple through the paper.

Paper clips are considered a heterogeneous mixture, as they are made up of different materials such as steel, iron, and sometimes zinc or nickel. These materials are physically mixed together and can be easily separated.

To remove ink from a Sharpie liquid pencil, you can try using rubbing alcohol or nail polish remover on a cotton ball or cloth. Gently dab the affected area with the solution until the ink starts to lift. You may need to repeat this process several times and wash the area with soap and water afterward.

Inhaling the fumes of a Sharpie can cause damage to brain cells due to the chemicals present in the marker, such as xylene and toluene. However, the exact number of brain cells that die from sniffing a Sharpie can vary depending on the individual and the amount of exposure. It's important to avoid inhaling any kind of fumes or chemicals to protect brain health.

Magnetic force. Nails and paper clips are often made of iron or steel which are attracted to magnets, allowing them to stick together.

Farmers use slaked lime in animal pens to help control odors, reduce moisture levels, and sanitize the environment. It can also help to neutralize acidic conditions caused by animal waste, creating a more comfortable and healthier living space for the animals.

Plastic pens are typically made of a combination of materials, including a plastic barrel, ink cartridge, and metal components such as the clip and tip. The plastic used in pens is often a type of polymer such as polyethylene or polystyrene, which provides durability and flexibility.

Paper clips are made of metal, typically steel, which has a higher density than water. This means that the weight of the paper clip is greater than the water it displaces, making it sink rather than float.

Yes, both metal paper clips and plastic paper clips are mixtures. Metal paper clips are made of metals like steel, while plastic paper clips are made of polymers like polypropylene. Both of these materials are composed of multiple substances mixed together to form the final product.

Sharpie markers contain a mixture of solvents, resins, and dyes. The specific composition is proprietary to the manufacturer, but typically includes substances like isopropyl alcohol, resin, and various pigments for color.

It's challenging to provide an exact number as production rates vary among manufacturers. However, on average, a single ballpoint pen manufacturing plant can produce tens of thousands to over a hundred thousand pens per day, depending on their size and capacity.

You can try using rubbing alcohol or hand sanitizer on a cotton ball to gently dab at the Sharpie stain on the leather chair. Test in an inconspicuous area first to ensure it doesn't damage the leather. Alternatively, commercial leather cleaners or even a specialized leather stain remover may also work.

• Magnetically: staples are magnetic and most of sand is not.
• Physically: put the mixture through a sieve of the correct size and the sand will go through, but the staples not.
• Physically: vibrate the container, and the less dense staples will move to the top.
• Chemically: add water and the salt should dissolve. If you don't leave it long enough for the staples to rust, then you can drain the water and retrieve the salt by evaporation.
• Manually: pick out a grain of sand, salt or a staple and put it in an appropriate pile.
• Pre-emptively: find the crazy fool who is mixing the staples and salt and sand, and stop her.

Pens today are typically made from a variety of materials such as plastic, metal, or a combination of both. The bodies of pens are often made from acrylic, resin, or metal alloys, while the tips or nibs can be made from materials like stainless steel or ceramic. Overall, pens are designed to be durable, functional, and aesthetically pleasing.

Plastic is a good material for pens because it is lightweight, durable, and inexpensive to produce. It can be easily molded into various shapes and designs, making it versatile for different pen styles. Additionally, plastic pens can come in a wide range of colors and finishes, appealing to a variety of preferences.

You can try using nail polish remover, rubbing alcohol, or a magic eraser to remove Sharpie from a notebook. Test a small area first to ensure it doesn't damage the paper. If all else fails, cover the Sharpie marks with a sticker or decorative tape.

There are several things to try. The trick is to find something that won't also dissolve the plastic, particularly since we don't know what kind of plastic it is. Try it on an inconspicuous area first. Rubbing alcohol might work and is unlikely to hurt the plastic. Terpene-based compounds would be a good second choice if the rubbing alcohol doesn't do anything. Try one of those orange or eucalyptus oil cleaners. Again, not too likely to hurt the plastic. Fingernail polish remover (generally a mixture of acetone and ethyl acetate) will probably work but is more likely to damage the plastic. Butanone (methyl ethyl ketone) will almost certainly work; however, it's also a pretty good solvent and will probably cause some damage.

The surface tension of water allows it to resist spillage when objects like paper clips are placed on its surface. The paper clips increase the water's surface tension by disrupting the normal bonding of water molecules, creating a barrier that helps prevent spillage.

Surface tension can typically hold up to around 20-40 regular-sized paper clips on the surface of water before breaking. This limit can vary based on factors like the size and weight of the paper clips, as well as the quality of the water surface.

i think it's HB pencil which is hardest one bcoz it is indiacative of its heat,hexagonal shape,measure of softness and wood quality

Pens run out when the ballpoint nib can no longer transfer ink to the paper effectively. This can happen due to a combination of factors such as air exposure, ball wear, and ink thickness. Once the ink flow becomes inconsistent, the pen is considered empty even though it still contains some ink.

Rubbing alcohol (or also called isopropanol/Ispropyl) is a solvent that has polar molecules (molecules with a positive charged molecule that sticks to a negative charged molecule).

If you sniff a sharpie, it has a sharp, alcohol smell, right? Sharpies have n-propanol alcohol, n-butanol, and diacetone alcohol in them. They have pretty similar structures to rubbing alcohol. All alcohol have polar molecules.

There is a "like dissolve like" rule. This means Polar solvent+Polar solvent=dissolve/removal. OR non-polar solvent+nonpolar solvent=dissolve/removal. The closer the molecule make-ups are, the more likely they are to dissolve or be removed.

All paper clips are not created equal and come in several sizes ranging from small to palm-sized and may be constructed of metal or plastic. A common size is approximately 2 cm or 3/4" long and made of steel. The weight of this standard, paper clip is about 1 gr. 5 would weigh 5 g.

The real IWAKO "made in Japan" Japanese Erasers are not toxic and are environmentally friendly. The knock off "made in China" are not!

In Canada, real Iwako "made in Japan" Japanese erasers are now available at independent toy stores across Canada. Just be sure to ask for Iwako "made in Japan" so you don't get the fake ones.
