How to Make a Green Fire Halloween Jack-o-Lantern

One application of green fire is using it to light your Halloween jack-o-lantern. This is a super-easy effect that produces spectacular results (watch the video). Heres how you do it: Key Takeaways: Green Fire Jack-o-Lantern The green fire jack-o-lantern is a colorful flame-filled Halloween pumpkin.The project involves dissolving a salt in a flammable solvent and igniting it.The green flame comes from the emission spectrum of the chemical. Either the boron ion or the Copper II (Cu2) ion will produce a green flame.The project should only be performed by adults. While the salts used in this project are not particularly toxic, they are not safe to eat. Methanol (methyl alcohol) is toxic and should not be handled or inhaled. Green Fire Jack-o-Lantern Materials You only need a few simple materials for this project: Carved jack-o-lantern. Traditionally this would be a pumpkin, but you could use a watermelon, cantaloupe, etc.Boric acid (usually found in pharmacy or pest control section of store)Methanol (such as Heetâ„ ¢ fuel treatment, found in the automotive section)Aluminum foil or heat-safe container that fits inside your jack-o-lanternLong-handled lighter Boric acid is a different chemical from borax (commonly sold as the laundry boost 20 Mule Team Borax). Pure boric acid is used to make a disinfectant solution and as a powder to kill and control cockroaches and other insects in the home. Boric acid dissolves better than borax in methanol, so it produces a better green flame. However, if you cant find boric acid, you can substitute borax and still get green fire. The green flame color is used in the flame test to help identify sample chemical composition. Nayef Hajjaj / EyeEm / Getty Images Other Substitutions Switching out borax for boric acid is not the only substitution you can make. You can use copper sulfate as the salt and a different alcohol for the solvent. Good choices include rubbing alcohol (contains one or more different alcohols), ethyl alcohol (ethanol), or isopropyl alcohol (isopropanol). These alcohols are less toxic than methanol, plus they contain water. The water is important because it dissolves the copper sulfate so it can color the flame. Copper sulfate is sold as a pure chemical and also as a root killing chemical. It is available online and at some home supply stores. The container should be labeled as copper sulfate, copper sulphate, or copper sulfate pentahydrate. If you get copper sulfate, you can also use it for other projects, such as growing blue copper sulfate crystals or making a copper sulfate geode. Fun Fact: The copper ion can emit either green or blue light. Cu2 is green, while Cu is blue. Unfortunately, changing the copper oxidation state is not a simple matter. It requires a series of redox reactions that could cant easily do at home. Start the Green  Fire! Technically all you need to do is sprinkle boric acid in a heat-safe container, add a little methanol, set the container inside the jack-o-lantern and light the fire. Its important to use a long-handled lighter, since the vapor pressure of methanol is very high and you will hear that whoof sound when you light the mixture. The best result, in my opinion, comes from lining the inside of the jack-o-lantern with aluminum foil and using the pumpkin as the heat-safe container. You can sprinkle boric acid inside the jack-o-lantern, splash a little methanol around, and light the decoration. The aluminum helps contain the liquid, plus it is reflective so it enhances the brightness of the display. Do not add more fuel to the burning fire; wait until it goes out. Safety note: dont do this indoors! Holiday Clean-Up Tips The green fire can get very hot, so there is a good chance your pumpkin will get somewhat cooked by lighting it this way. The methanol is burned away by the fire, leaving some boric acid residue with your pumpkin. While boric acid is not particularly toxic, you dont want kids or animals to eat this jack-o-lantern, nor is it ideal for compost since too much boron can be toxic to plants. Be sure to throw your jack-o-lantern away before it rots in place. Just remember the pumpkin contains boric acid, so dont let anyone eat it.

Comparing The Millers Tale and The Reves Tale Essays

Similarities in The Millers Tale and The Reves Tale The Millers Tale and The Reves Tale from The Canterbury Tales are very closely related. They both deal with the relationship between a jealous man, his wife, and a young scholar(s), and they both are immoral stories that contain sex and violence. This proves that the Miller and the Reeve are two very corrupt individuals. However, these tales also share some differences. For instance, the main character in The Reeves Tale is a Miller, while the main character in The Millers Tale is a carpenter (which was the Reeves profession), and both tales are different in the way the Miller and the Reeve are portrayed. Again the differences†¦show more content†¦For instance, The Millers Tale contains several different occasions of lying and cheating, including the scene where the Miller cheats Alan and John out of a fair amount of grain, and the scene where John moves The Millers wifes baby to confuse the her into sleeping with him. In comparison, The Reeves Tale has a similar amount of dishonesty. For instance, in an elaborate attempt to sleep with the Carpenters wife, Nicholas tells the Carpenter, Rain is to is to fall in torrents, such a scud / It will be twice as bad as Noahs Flood (97). Nicholas, goes on to tell the Carpenter to build a boat that will carry him and his wife when the rain comes. However, this narrative is completely fabricated, so he could visit the Carpenters wife while the Carpenter is asleep in the boat. This is a good example of how the two tales share similarities in conjunction to sexuality and immorality. This similarity also reflect s upon the tales author, by offering sexuality and immorality as another corrupt characteristic. Although, The Millers Tale and The Reeves Tale appear to have similarities, they do share some differences which reveal a lot about the tales teller. As an example, both tales contain a wife, a scholar(s), and either a Carpenter or a Miller. However, when closely examined, the non- coincidental
