Images from laboratory four
The basic set up: hot water in the large cup, room temperature water in the smaller cup.
The new HTML 5 img alt recommendation is being followed. The alt in the following image does not describe the picture, it is a sentence that flows naturally in the context of the surrounding prose when the image does not show. The title remains the tooltip text at least for FireFox.
There is a <br> tucked in the code below. This is a kludge to get around browsers not yet recognizing legend tag. For this reason, the legend tag follows the image and thus differs from usage I've seen in an article by Elliotte Rusty Harold. Unsure how to keep browsers maximally happy, I have enclosed the figure in a <p> block.
Styling the legend tag in the external css does not yet work in FireFox 2.0.0.6
Nor does adding the style command to the legeng tag: FF is simply ignoring the tag. Still, this is graceful degradation at its best. New tags back from the future are not throwing FF for a loop.
The conductors are hardware store finds: sections of six gage solid copper electrical wire, a zinc wall board fastener.
The lead bolt mount leaked badly, both onto the table and, later in the 11:00 section, across through the glue. By 11:00 so much glue was on the rig that the lead was no longer in sigificant contact with the water. And the water then leaked from the hot cup (higher water level) into the lower cup though some "tunnel" in the glue. Lead was simply problematic in both sections.
