How to Start Green Fire With a Drop of Water
How to Start Green Fire With a Drop of Water You dont need a match to start a fire. In this project, start a fire by adding a drop of water to a dry chemical mixture. The best part? The flames will be green! Fire Safety You should be able to tell from the premise that thisà is an adult-only project, best performed by someone with prior pyrotechnic project experience. Follow the instructions carefully to minimize the risk of a fire. Youre using water to start a combustion reaction, so keep your materials away from moisture, soft drinks, perspiration, etc. Got it? Green Materials Instant cold pack (3 grams ammonium nitrate)7 grams zinc filings or powder1/2 gram table salt (sodium chloride)Mortar and pestle If you dont have a cold pack, you can use pure ammonium nitrate, which is available online. You can buy zinc filings or powder online or you can sand a galvanized piece of metal from a hardware store to get the element. If you have to file or sand the zinc, its a good idea to wear a mask, such as the kind used for home repair,à so you dont inhale zinc particles. Procedure for Starting the Green Flames Open the cold pack. Remove and discard the bag of water. Open the bag of ammonium nitrate. Measure out 3 grams of the granules and put them in the mortar.Add 1/2 gram of sodium chloride (salt).Use the pestle to grind together the salt and ammonium nitrate to form a powder.Carefully grind the 7 grams of zinc powder into this mixture. Water can ignite the mixture at this point, so dont spill your drink or drip sweat into the powder. Its a good idea to wear disposable plastic gloves, because you dont want the final mixture reacting with water on your hands.Transfer the mixture to a metal or otherwise fire-proof container. Take it outdoors to start the reaction. Use a pipette or other long-handled dispensing device to add a few drops of water. The reaction can be spectacular, so move back immediately. Another reaction you can do using these materials is to mix ammonium nitrate with zinc and initiate combustion by adding a few drops of hydrochloric (muriatic) acid.

Super Bowl Slang Get It Right!
Super Bowl Slang Get It Right! Football has a language of itââ¬â¢s own, and not knowing it can make you feel like an alien from another planet. Fortunately, youââ¬â¢ve been around long enough to know what a touchdown looks like, what happens when a QB gets sacked, or how to recognize the ââ¬Å"snap.â⬠Instead of Football Terminology for Dummies, you need a specific set of new vocabulary to get you prepared for Superbowl 49. That way, youââ¬â¢ll know exactly whatââ¬â¢s going on when the Patsies and the Seachickens have their final showdown. Blitz This is when the defense of a team sends an angry mob after the quarterback. Teams that tend to stack the line of scrimmage with rush linebackers instead of defensive players may be looking to aggressively blitz. This is also called ââ¬Å"The Psycho Defense.â⬠Goal Line Stand This happens when the defense continually stops the offense just before it gets into the end zone. The goal is to hold the offensive team and get them to waste their downs to force a turnover. Hail Mary This is the ââ¬Å"miracle playâ⬠that dreams (and dollars) are made of. Itââ¬â¢s a long, desperate pass by the QB to a player at the other end of the field. It doesnââ¬â¢t work very often, but when it does, your mind is blown away by sheer awesomeness. Pick Six When the offensive team throws a pass that is intercepted and then taken downfield by the defending team for a touchdown. This is a completely exhilarating play, unless youââ¬â¢re on the offensive team. Then, itââ¬â¢s just embarrassing. Sam, Mike, Will Every team will have these guys as players, even though theyââ¬â¢ll never show up on the roster. These are all names for typical player positions on the field, and are derived from the initials of the position. In a 4-3 alignment, with four lineman in the front and three behind, the strong-lined linebacker is Sam, the middle linebacker is Mike, and the weak-lined linebacker is Will. Leo/Elephant Similar to Sam, Will, and Mike, this is a position on the field, although it is not necessarily a linebacker or defensive position specifically. It is derived from the terms ââ¬Å"linebackerâ⬠and ââ¬Å"end,â⬠and the organization of the letters specify when the position is more defensive or offensive. Jack This, too, is a moniker for a player position, although it is not truly specified. The Jack, or ââ¬Å"jack of all trades,â⬠is a surprise position, usually not revealed as defensive or offensive until the play is in motion. Deflategate Following the AFC championship game between the New England Patriots and Indianapolis Colts, NFL referees investigated a tip that some of the game balls had been deflated by the Patriots. This is a violation of the NFL rule that requires balls to be inflated between 12.5 and 13.5 pounds per square inch. Eleven of the 12 balls used during the game were found to be underinflated, potentially giving the Pats an edge over the competition. Legion Of Boom Due to the hard-hitting nature of the Seattle Seahawks defense, they have been dubbed by sports aficionados as the ââ¬Å"Legion of Boom.â⬠Members include all defensive backs, including Richard Sherman, Kam Chancellor, Earl Thomas, Byron Maxwell, and Brandon Browner. Evil Empire This is a derogatory term in reference to the New England Patriots, especially in light of Coach Bill Bellichickââ¬â¢s ââ¬Å"Spygateâ⬠scandal, which led to a $25,000 fine for his illegal taping of opponentsââ¬â¢ plays. Bellichickââ¬â¢s consistent wearing of hoodies during games added to the effect, giving him the nickname of ââ¬Å"Emperor Bellichick,â⬠the evil lord of the Patriot Empire. Gronk Spike, The Gronk New England Patriot player, Rob Gronkowski, is known for his violent treatment of a football once itââ¬â¢s in the end zone. In fact, Gronkowski claims that his excessive force is one of the reasons why Deflategate occurred, tweeting a meme, ââ¬Å"Warning: Gronking may cause deflation.â⬠Patsies This is the favored slur for the Patriots when the team is not playing very well. Others include the Evil Empire, Homeland Defense, Tea Men, Pattycakes, and Patties. Seagulls This is the favored slur for the Seahawks when the team is not playing very well. Others include Seachickens, Cheesehawks, Seahacks, and Water Rats. Tom Terrific A nickname given to Tom Brady due to his impressive history of amazing game-play: 3 Super Bowls, 2 League MVPs, 2 Super Bowl MVPs and the regular season record for passing touchdowns. Superbowl 49 will be his sixth. Beast Mode Marshawn Terrell Lynch is a running back for the Seahawks, and one of the most aggressive running players in the league. He is nicknamed ââ¬Å"Beast Modeâ⬠due to his ability to break tackles and bones alike. The 12th Man, or The 12s This is a nickname give to the Seahawk fans because of their ability to scream so loudly they often cause the offensive lineman to false start. They are such a huge part of the Seahawksââ¬â¢ success, supporting the 11 field men so passionately, that they have been dubbed ââ¬Å"The 12th Man.â⬠The Seahawks retired the number 12 jersey in 1984 in appreciation of their fans.
