A company specialising in camping equipment
has researched different difficulties that campers come
across and decided to tackle some of these problems.
In windy weather things such as bottles and glasses
may easily be blown away from the table.
As a designer you are asked to design an innovative
artefact to hold a bottle of water and a few glasses on
the table without being blown away.
