'''Portable Star Labs''' are the method by which new [[Stars|Star Recipes]] are created for use in the [[Test of Pyrotechnics]]. Using a Portable Star Lab is not required for either the principle or the Test of Pyrotechnics.  It is an independent tool that any Egyptian can use to contribute to the variety of stars that are available to everyone. Here's how.

Each University of Art and Music starts with the same two basic [[Stars|Star Recipe]], and can gain additional recipes using Star Labs. Each University that has opened the [[Mortar Construction]] technology will distribute approximately two '''Portable Star Labs''' to players per week, apparently at random intervals. After use, a lab can be turned in at any University of Art and Music that has opened [[Mortar Construction]] (note: not necessarily the one from which it was received). Once a SINGLE University of Art and Music has received SEVEN (7) labs, the scientists will select one of the seven submitted stars, and players will then be able to learn that [[Stars|Star Recipe]] from that University, and only that University.  

== Use ==

Star labs are pre-loaded with materials to fire 60 shots. After each shot, the owner is given the option of:

* naming the shot that was just fired, 
* selecting the shot that was just fired as the best so far, 
* refiring the last shot without changing it, 
* or firing a new random shot. 

Players other than the owner can register as watchers of the display, and will be able to see the stars as they are launched, and read the costs of the most recently launched star. The owner of the lab has sole discretion over which star is selected as the "best" - it is not a voting process - but typically the owners solicit input from the watchers and make a collaborative decision. Once a final decision has been made and named, the lab can be turned in at a University of Art and Music. At this point, the number of watchers becomes important: this number is a weighting factor on how likely it is that that particular [[Stars|Star Design]] will be selected, once 7 total have been turned in. (Example: six labs are turned in with 1 watcher, and a seventh is turned in with 14 watchers. There will be a 70% chance that the seventh lab is the one selected)

Please note '''that registering as a watcher but not being present for the using of the lab is not effective'''. The lab only counts those that have registered and are within range (<25 cords) of the shot fired as having watched that star. Therefore, leaving a star lab on the road to accumulate watchers is of no real value (unless those that register return for the using of the lab). 

== Types of Stars  & Cost==

Star labs seem to produce several basic kinds of stars: (not an exhaustive list yet)

* '''Pulsing stars''' - these have a strong glow on the first star, and usually leave a simple trail. There is considerable variability in the size of the star, and the length of the trail. The basic frog and canary designs are this type.
* '''Cone stars (comets)''' - Have a strong glow at the front, and diffuse into a short 'cone' shape.
* '''Bomb stars (poppers)''' - these are often hard to see, since they fly their lifetime unignited, and then explode at the end. Single poppers are useful as near-invisible platforms for delivering other stars, while showers of many poppers can be an impressive finale.
* '''Trails ("Thin Red Line")''' - long thin trails of light, often used for spirals and geometric shapes.
* '''Sparkler Stars''' - these are typically crowd favorites. They leave a shower of sparks as a trail, usually but not always in the same color as the head of the star. 

Stars are typically a single basic color, but there are occasional instances of two-color stars. In some cases, both colors are present in the star, and in others, the star has a multi-coloured trail.

Star Costs: Stars seem to have their costs randomly generated, along the following parameters:

* some quantity of one of the four binding materials ([[Clay]], [[Beeswax]], [[Cactus Sap]], or [[Tar]])
* some quantity of [[Sulfur]]
* some quantity of [[Charcoal]]
* some quantity of 1 or 2 types of [[Metal Salts]] (range 5-250? [[Metal Salts]] per 10 [[Stars]]) - normally 1 salt type for most [[Stars]], but two-color [[Stars]] will have two [[Metal Salts]] types.
* [[Aluminum Powder]] (range 5-250? powder per 10 stars) - this is only required on sparkler- or bomb-type stars, as described above. 

See [[Stars]] for list of known Stars, Costs and University locations.

Notes:

* Star Labs need not be returned to the same University of Art and Music from which they are received. It is preferable that they ALL be returned to the same University, so that we can maximize the number of new stars opened, and players can learn all new recipes at one place. 
* Turning in one lab is independent of the university producing another lab (e.g. it is possible for a university to produce a second lab before the first is turned in, or even before the first is requested by a player, but the latter seems quite unlikely)
* There is no known game benefit to having or using a star lab, outside of its intended purpose of returning it to a university. '''Please don't keep them'''.
* Make sure you don't leave the nomination of a favourite until the end, one cannot go back and you risk losing your star lab. Any favourite nomination is overwritten by a new favourite, so you can nominate the first one that looks half decent and then nominate a new one if you get a better one later.
* When you turn in a lab, they might want you to rename the favorite star, if that name has been used already on a Star Lab. You can rename the favorite through the utility menu on the portable star lab.
