 AnneMarie Maes and Frank Raes work together on the project 'Cloud in a Box', which displays a small pure
  cloud emprisoned in a glass container.{{:cloud:cloud-in-a_box_model-1.jpg?400|}}
+The idea is to make a small orographic cloud in a box.
+Modelling could give the parameters: temperature gradient, air velocity, expansion and cooling rate, ... under which it would theoretically be possible?
+If not an "orographic cloud", would there be other ways to create a permanent cloud in a box?
+A couple of thoughts:
+- one way we do produce a cloud in a box or bottle is to pump down the pressure and then allow air to rush in , the adiabatic cooling does then produce a cloud for a short period. The big issue is that the cloud is very transient due to rapid loss of droplets to the walls.That is always going to be an issue.
+- another method of obtaining a stationary cloud might be to blow a mixture of steam and cold air through the box as shown in the above diagram.
+DIY oplossing:
+stoom en koude lucht tegen elkaar in blazen.
+Daarvoor zou dan "alleen" een luchtcompressor nodig zijn + een kookketel + box.
