Cloud Chamber Build

Building the cloud chamber meant that we had to research how build one, and then get the materials to build it.  That meant getting felt cloth, a fish tank, styrofoam for insulation, a black marble floor tile and duct tape.  We decided to use black so that the fog of the cloud chamber would show up agains the black.  We also lined the tank with black paper for the same reason.

Here are Owen and Maanik making the insulation for the base of the tank, which has to be kept really cold - we used dry ice that Drew's father got us.  That turned out to be a lot of fun, so we gave it its own blog post, which you can read here.

We worked on building the cloud chamber for two or three weeks, and figured out that dry ice doesn't do enough by itself to make the cloud that we were hoping for.  In our next post, you can see that we figured out how to make good clouds.  By the way, this photo is Drew and Owen working on building the bottom of the chamber.
