1. Introduction
   
   Have you ever seen foam on the beach and wondered what it is and where it comes from?
   
   This activity is perfectly adapted to use it on a stand in order to deliver simple and quick information on eutrophication to family audiences. It can even last less than 15 minutes.
   
   
2. Experiment
   
   This short activity is easy to handle and requires simple material such as:
   - photos to show foam and the unicellular algae Phaeocystis,
   - a plant in clay pot with stickers to represent the plant growing needs,
   - illustrations of the water cycle to explain people that everything goes to the sea, and
   - the white of an egg to mimic the foam phenomenon.
   
   
3. This tool is designed for adults and children from 7 years old.
