I made a magnetic needle box. I made this for old and used needles. In space there is no gravity. So, the magnet in the bottom of the box hold all the needles in it. The box has a diameter of 8 inches. The hole that you put the needles in is a 0.5 in x 0.5 in square. Because of the small hole nobody can stick their fingers in it and get old needles out to use. That is what the magnetic needle box is.
