Script name

Thirsty man

Length

1251 frames

Description

A man joins the scene dragging on the floor towards a big glass seemingly full of water. However, when he is on the point of drinking it, he finds no water but and old crumpled page of a newspaper inside. He spreads and inspects it thoroughly like trying to find out an explanation. Then, completely confused, he crumples it again and wrings it over its head, willing to get at least a few drops to quench its thirst. But he cannot get anything ending up falling into a faint. After a while someone seems to take pity on this man and throws a juicy orange into the scene which seems to revive him.

This script is mainly intended to show:

  • Textured size varying (news-paper spreaded page) and non textured, rigid and non rigid objects interacting
  • Objects moving at different velocities (the finally thrown apple will have a significantly high speed)
