     You need 3D glasses to see some films. I think it is easy to make your own 3D glasses instead of buying
them.
      There are two ways to make 3D glasses. You can decide which way would be easier for you.
      The first way seems like the cheaper way but the things needed to make the glasses this way may not be
things laying around the house. First print out a template(模板) for the glasses at
http://paperproject. org/ PDF files/3 dglasses. pdf. 
     After you cut out the template, cut your cellophane (玻璃紙) to fit the holes in the glasses. Make sure you
place the red cellophane on the left eye and the blue on the right. You can either stick or tape the cellophane in
place. You are now ready to use your glasses.

     Another way you can make 3D glasses is to find an old pair of sunglasses. Take out the lenses(鏡片).
Get a piece of clear plastic and place the lenses on it, draw a line around the lens and then cut the new
plastic lens out. Place the lens back into the sunglasses frame (框). Color the left lens red with a marker
and the right eye blue. You now are ready to watch 3D films.
