Leprechaun Trap - Green Slime St. Patricks Day Project
Leprechaun Trap - Green Slime St. Patricks Day Project Heres how to make green slime for St. Patricks Day leprechaun trap. We havent successfully caught any leprechauns using this recipe yet, but it does make a nice holiday chemistry project for kids! Leprechaun Trap Slime Materials 4-oz bottle school glue gelborax (not boric acid)watergreen food coloring Make the Leprechaun Trap Slime Solutions The leprechaun trap is made by mixing two solutions together, which cross-link or polymerize to make a gel or slime. First, make the solutions: Borax Solution Take about a half cup of hot water and stir in borax until it stops dissolving. It is fine if the solution is cloudy or if there is undissolved solid at the bottom of the container. Just add the liquid part to your slime recipe. Glue Solution You can make either opaque slime or translucent slime, depending on the type of glue you use for this project. White glue produces an opaque slime. Clear or translucent blue glue will produce a translucent slime. You can color either type of slime using food coloring. Stir 4-oz of glue into 1 cup of water.Add a couple of drops of food coloring. The radioactive chemistry green-yellow color is obtained by adding 2 drops of yellow or 2 drops yellow and 1 drop of green coloring, depending how green you want the slime. For a leprechaun trap, you can add a few drops of green food coloring and call it good. If youre a rebel, dye the slime blue! Blue was the traditional Irish color before green came into vogue. Make the Leprechaun Trap Simply mix together 1/3 cup of the borax solution and 1 cup of the glue solution. You can use your hands or you can use a spoon. Glowing Leprechaun Trap What leprechaun wouldnt be attracted to a glowing trap? You can make the slime glow very brightly under ultraviolet or light if you add a little yellow highlighter ink to either of the solutions. Highlighter ink is fluorescent, so it emits light when exposed to high-energy light. Note adding the contents of a glow stick will not work, because the other chemicals in the slime will interfere with the reaction that produces the glow. Cleaning Up the Leprechaun Trap Although regular slime doesnt stain most surface, the food coloring you added to make it green will stain clothing, furniture, and counters. You can remove the color from countertops using cleaner with bleach. Except for the food coloring, slime washes away with soap and water or in regular laundry. After St. Patricks Day Your leprechaun trap wont last until St. Patricks Day next year, but if you seal it in a covered bowl or a plastic bag, it will be good for several days. You can extend this to a couple of weeks if you store the bag in the refrigerator. The sealed bag keeps the slime from drying out while the refrigerator keeps it from developing mold. How Leprechaun Trap Slime Works When you mix the glue and the borax the polymer in the glue, polyvinyl acetate, undergoes a chemical reaction. Cross-linking bonds are formed, causing the glue stick less to your hands or spoon and more to itself. Feel free to experiment with the amount of glue, water, and borax that you use to make the slime. You can adjust the recipe to make the slime more fluid or more stiff. The molecules in the polymer are not fixed in place, so you can stretch the slime quite far before it will break or tear.

Lycurgus - Spartan Lawgiver
Lycurgus - Spartan Lawgiver Dateline: 06/22/99 Back to Sparta: A Military State Although the evolution of Greek law codes is complicated and cant really be reduced to the work of a single individual, there is one man who stands out as responsible for Athenian law and one for Spartan law. Athens had its Solon, and Sparta had its Lycurgus the lawgiver. Like the origins of Lycurgus legal reforms, the man himself is wrapped in legend. Herodotus 1.65.4 says the Spartans thought the laws of Lycurgus came from Crete. Xenophon takes a contrary position, arguing Lycurgus made them up; while Plato says the Delphic Oracle provided the laws. Regardless of the origin of the laws of Lycurgus, the Delphic Oracle played an important, if legendary, role in their acceptance. Lycurgus claimed that the Oracle had insisted the laws not be written down. He tricked the Spartans into keeping the laws for an ostensibly short period while Lycurus went on a journey. Because of the authority invoked, the Spartans agreed. But then, instead of returning, Lycurgus disappears forever from hi story, thereby eternally obliging the Spartans to honor their agreement not to change the laws. See Sanderson Becks Ethics of Greek Culture for more on this. Some think the laws of Sparta were essentially unchanged until the third century B.C., with the exception of a rider to the rhetra quoted by Plutarch. See Legislation in Sparta, by W. G. Forrest. Phoenix. Vol. 21, No. 1 (Spring, 1967), pp. 11-19. Source: (amherst.edu/~eakcetin/sparta.html) Lycurgus Reforms and the Spartan SocietyBefore Lycurgus there had been dual kingship, division of the society into Spartiates, Helots, and perioeci, and the ephorate. After his travels to Crete and elsewhere, Lycurgus brought to Sparta three innovations: Elders (gerusia), Redistribution of land, and Common messes (meals). Lycurgus forbade gold and silver coinage, replacing it with iron coinage of low value, making trade with other Greek poleis difficult; for instance, there were supposedly loaf shaped and sized iron coins. It is also possible that the iron coins were valued, as iron had been in the Iron Age of Homer. See The Iron Money of Sparta, by H. Michell Phoenix, Vol. 1, Supplement to Volume One. (Spring, 1947), pp. 42-44. Men were to live in barracks and women were to undergo physical training. In all he did Lycurgus was trying to suppress greed and luxury.[www.perseus.tufts.edu/cl135/Students/Debra_Taylor/delphproj2.html] Delphi and the LawWe dont know whether Lycurgus asked the oracle simply to confirm the law code he already had or asked the oracle to provide the code. Xenophon opts for the former, while Plato believes the latter. Theres a possibility that the code came from Crete.Source: (web.reed.edu/academic/departments/classics/Spartans.html) Early SpartaThucydides suggested that it was not the kings who declared war, and the fact that seven helots attended each Spartan indicates the helots lot may not have been so bad. The Great RhetraPassage from Plutarchs Life of Lycurgus on his obtaining an oracle from Delphi about the establishment of his form of government: When thou has built a temple to Zeus Syllanius and Athena Syllania, divided the people into phylai, and divided them into obai, and established a Gerousia of thirty including the Archagetai, then from time to time appellazein between Babyka and Knakion, and there introduce and repeal measures; but the Demos must have the decision and the power. Xenophon on the SpartansNine passages from Herodotus about the famous Spartan lawgiver Lycurgus. Passages include notice that female slaves were to work on clothes while free women, since production of children was the noblest occupation, were to exercise as much as the men. If a husband were old, he should supply his wife with a younger man to beget children. Lycurgus made it honorable to satisfy natural cravings by stealing; he forbade free citizens from engaging in business; failing to do ones duty would result in loss of status of the homoioi, (equally privileged citizens).
