There are many video recordings of experiments available on the web that look like magic tricks.
These experiments can be very attractive for pupils. However, their explanation can be missing,
wrong or may lead to misconceptions. One of these is a video guide How to make a hologram using a
smartphone. In this paper, we present the experiment that results in creating an impression of a
hologram. Detailed exploration of the created hologram can reveal the true nature of the generated
image.
