− | This is a modified version of the {{w|phase diagram}} for {{w|water}}. A "phase diagram" is a chart that shows the states, or "phases", that a substance will be in under various temperatures and pressures. {{w|Ice#Phases|Water's phases}} are particularly well-studied; on the [ | + | This is a modified version of the {{w|phase diagram}} for {{w|water}}. A "phase diagram" is a chart that shows the states, or "phases", that a substance will be in under various temperatures and pressures. {{w|Ice#Phases|Water's phases}} are particularly well-studied; on the [http://ergodic.ugr.es/termo/lecciones/water1.html real phase diagram for water], there are a great many phases listed. |
− | Most people are familiar with three phases of water — solid ({{w|ice}}), liquid (water), and gas ({{w|Water vapor|vapour}}) — and with the fact that an increase in temperature will cause water to change from one state to another. The gas and liquid phases are quite straightforward; however, there is in fact not one single solid phase of water, but a variety of numbered phases ("ice I" through "ice | + | Most people are familiar with three phases of water — solid ({{w|ice}}), liquid (water), and gas ({{w|Water vapor|vapour}}) — and with the fact that an increase in temperature will cause water to change from one state to another. The gas and liquid phases are quite straightforward; however, there is in fact not one single solid phase of water, but a variety of numbered phases ("ice I" through "ice XV" are currently recognized), several of which are divided into sub-categories. Ordinary, everyday ice is known as "{{w|Ice Ih|ice I<sub>h</sub>}}" ("ice one-h"). Most of the more unusual forms of ice only form under very {{w|high pressure}}. |

For one, | + | [[Randall|Randall's]] phase diagram starts out realistically, though slightly simplified in several ways. For one, it simply uses the name "ice" for the usual form(s). It is focused in on a narrower area than the more complete diagram linked earlier; on that version, the "ice V" region is quite small, and "ice III" is barely visible, whereas both are quite plain to see on Randall's diagram. Lastly, where most phase diagrams have pressure increase upwards, Randall has the pressure scale increase downwards, this has been chosen to make it possible for the jokes to appear at the bottom of the chart. Else the comic would not be funny for the average reader. |
Because, as the diagram continues downwards and the pressure increases, the jokes begin. Beyond the moderately high-pressure forms of ice (ice II, III and V), a real phase diagram has ice VI; Randall has "Vanilla Ice (ice VI)". {{w|Vanilla Ice}} is the stage name of a white rap/hip-hop artist from the 1990s; the initials of Vanilla Ice, and the Roman numeral six, are both VI. | Because, as the diagram continues downwards and the pressure increases, the jokes begin.

Vanilla Ice's biggest hit, "{{w|Ice Ice Baby}}", used samples from the earlier song "{{w|Under Pressure}}", by {{w|David Bowie}} and {{w|Queen (band)|Queen}}; accordingly, on Randall's diagram, the "Vanilla Ice" region transitions to "David Bowie & Queen" when it is under (even higher) pressure. | Vanilla Ice's biggest hit, "{{w|Ice Ice Baby}}", used samples from the earlier song "{{w|Under Pressure}}", by {{w|David Bowie}} and {{w|Queen (band)|Queen}}; accordingly, on Randall's diagram, the "Vanilla Ice" region transitions to "David Bowie & Queen" when it is under (even higher) pressure. | ||
− | Further references to "Ice Ice Baby" are found in the title text. Near the beginning of the song, Vanilla Ice raps the line, "All right stop, collaborate and listen". The unusual choice of "collaborate" in this line has made it memorable, and the word is used in the title text (in a more typical context). The phrase "survive at room temperature for several months" is likely a reference to "Ice Ice Baby" being Vanilla Ice's only major hit, humorously suggesting he faded out of the public view after a few months of fame.

It also contains a reference to the songs "Under Pressure" and "Ice Ice Baby" in one figure. |
The title text of [[1434: Where Do Birds Go]] whimsically suggests another possible phase of water/ice. | The title text of [[1434: Where Do Birds Go]] whimsically suggests another possible phase of water/ice. | ||
