Ballpoint pens don't work on film because the surface of the film is too smooth and non-porous for the ink to adhere to. The ink from a ballpoint pen needs a slightly rougher and more absorbent surface to be able to stick and dry properly. Additionally, the ink from a ballpoint pen may not be visible on the transparent surface of the film, making it ineffective for writing or drawing. Therefore, other types of pens or markers specifically designed for use on film, such as permanent markers or overhead projectors pens, are typically used instead. **

Ballpoint pens do not work well on overhead transparencies because the ink in ballpoint pens is oil-based and does not dry quickly on smooth surfaces like transparencies. This can cause smudging and smearing of the ink, making it difficult to write or draw clearly. Additionally, the plastic surface of transparencies does not absorb the ink like paper does, leading to poor adhesion and legibility. It is recommended to use permanent markers or special transparency pens designed for writing on overhead transparencies to ensure clear and lasting results. **
