Telescope

    In science yesterday it had me make a telescope. I made it out of, paper towel tubes, and 2 magnifying glasses. They project the image upside down, but that is because when two of the same lenses are put together, (concave and concave or Convex to convex) it refracts the light and makes it upside down. The telescope is hard to use, because the lenses are the same size, it effects it, and they are as I said before concave lenses. but it works!
