see the video
<p>might you be able to use this as a cloud chamber to observe particle tracks, you would need to have the bottle in the state where it is just about to form a cloud but nucleation sites are lacking.</p>
Yeah, i think Here's something wrong. Only titel Step 1 after that.
<p>there are no directions. just a list of items.</p>
