Impress your friends with a DIY projector made from a shoebox. Trace a hole in the shape of a magnifying glass on one of the short ends of the box. Once the hole is cut, secure the lens of the magnifying glass into place with tape. Position your phone inside, but remember to change your phone settings so you can flip the screen—the picture from your projector will be upside down. Put the lid on the box, dim the lights, grab some popcorn, and enjoy.
