Some effects use mechanical tools to move things. A gimbal can make the ground move. Aerial rigging can make a person look like they fly. These tools change the world around the actors.

Artists also use many clever ways to make creatures. They might use prosthetic makeup on a face. They can use masks or even creature suits. Some use puppetry to move a character. Others use animatronics, which are machines that move.

These tools make non-human things look real. This is different from computer-made images. It is a physical way to build a monster.

Action scenes often use very specific tools. Pyrotechnics are used for fire and big explosions. To show a gunshot, workers use squibs. A squib is a small packet of fake blood. It pops to make a wound look real.

Filmmakers also use miniature effects for big things. These are small scale models of buildings or cities. The camera films them to make them look huge. This makes a small model look full sized.

Making these effects is a very big job. It requires many different kinds of skills. Workers must be artists and craftsmen. They also need to know about engineering. They use mechanics to make machines work.
