Traditionally, hourglasses have been made using two glass bulbs connected by a narrow neck to allow sand to flow from one to the other. The glass bulbs were often sealed with wax or glass to prevent the sand from leaking. The sand used inside an hourglass is usually fine-grained and able to flow smoothly through the narrow neck.

What materials are used to make space shuttles?
Space shuttles are primarily made of aluminum alloys, reinforced carbon-carbon (RCC) for the heat shield, and thermal protection tiles. The external fuel tank is made of aluminum and the solid rocket boosters use a combination of aluminum, steel, and composite materials. Various other materials such as titanium, ceramics, and specific polymers are also used in different components of the space shuttle.
What materials are used to make a telescope?
Telescopes are primarily made from glass or optical materials for lenses and mirrors, which are essential for focusing light. The structure is often constructed from aluminum or steel for durability and stability. Additionally, materials like plastic or composite materials may be used for various components, such as mounts and housings, to reduce weight and improve portability. For advanced telescopes, specialized coatings and technologies can be applied to enhance performance.

How is math used in an hourglass?
Math is used in a hourglass to make sure you have the proper flow rate for the desired amount of time. If the sand flows too fast then you need to make a smaller opening, if to slow you need too make a wider opening or add more sand.
