In today's highly technological world, we deal with a wide variety of daily necessities every day. But have you ever wondered what hidden mysteries lie behind these seemingly ordinary and mundane objects? Perhaps you haven't been aware of the new quirks. For example, you may never notice your ordinary eraser, which is one of the most frequently used items in our schools and offices. But you know what? Ordinary erasers are actually made from a mixture of special chemical materials, and their rare formula is that the erasers can easily erase ink, pencils and even brightly colored pigments. Take a look at the scissors you have at hand. This is an innovative product, designed through complex engineering principles. When you close the scissors, the two pieces of steel create enough friction to easily cut through paper, fabric, and even plastic. The curious thing about groceries is not just their science, but how they meet our needs in life.

Only when you start paying attention to the details of the science, art, and design behind these common objects can you truly appreciate their charm and value. So let's celebrate the novelty of these everyday items that truly blend technology and art to comfortably serve our daily lives.
