it took from 1961-1962 to build the Seattle space needle (1year)!!
The space needle was build in the 1940's for the world fair. The theme of the fair was the future. The person that build the needle wanted to make some thing that would make people of space. So he named it the space needle.
wood 2nd answer: The Space Needle in Seattle is made of concrete, steel, aluminum, and glass, with some wood trim inside.
they used fabrics from flax and a needle and wove it

To make it stand, she holds it, to make it smooth, she licks it, to make it enter, she pushes it in....it's not easy to thread a needle.
You need to rub the needle with a magnet or you can use coil around the needle and pass current to make it a electro magnet.
needle
Rub the needle across a magnetic surface...always in the same direction, don't go back and forth. This will magnetise the needle. Then float the needle in a dish of water. And presto you have your own compass
To make an ordinary sewing needle into a compass needle, it must first be demagnetized by heating it to a high temperature and then allowing it to cool in a specific orientation. This aligns the needle's magnetic domains and makes it a more effective compass needle.
To magnetize a needle, you can rub it against a magnet in the same direction multiple times. This will align the magnetic domains in the needle and make it magnetic.
magnetize a needle by rubbing it on a magnet. Lie the needle in a shallow container of water, allowing the surface tension to keep the needle afloat. The needle will orient to north and south
You can learn how to make a needle by researching online tutorials, taking a class on metalworking or blacksmithing, or seeking guidance from a skilled craftsman. Practice and patience are key to mastering the art of needle-making.
