 How to un-jam a print queue:

     From the start menu, select run. Type CMD, click OK and type net stop spooler. While leaving the CMD window still open, wait a few seconds then check the print queue. It should now be cleared. Finally type net start spooler in the CMD box. 

Chemistry

 How to make thermite: 

     The first thing you need are the ingredients:  a metal oxide, a more active pure metal, and an ignition source. The metal oxide can easly be procured. Some types such as Iron (III) Oxide, Fe₂O₃ (also known as Hematite), or Iron (II, III) Oxide, Fe₃O₄ (also known as Magnetite). Also, Copper (II) Oxide, Tin Oxide, Lead Oxide, or any other metal Oxide which could be reacted with a reducing metal can be used. The more active pure metal, or reducing metal, such as Aluminum or Magnesium powder, is used to melt and make the metal oxide burn. To ignite the thermite, you need a fuse. This is because of two things; thermite reacts so violently and so hot, you don't want to get hit by any chunks of molten metal. The other is that the ignition temperature is very high, which you can't reach with a simple blow torch. I find the easiest way to light it is to use mangnesium ribbon. This is because it can be lit with a match, but burns hot enough to ignite the thermite. Place a strip of magnesium ribbon (which can be bought online) into it and light it. The magnesium burns slowly so you can take your time, just get a ways off before the thermite ignites.

How to procure lithium metal:

     This is pretty easy, if you do it right. First off, though, lets talk about lithium. It's an alkali metal, meaning it reacts violently with water. This means any humidity may cause it to go up in  flames.

     Now that I've said this, we can begin. First, buy some new litium- ion AA batteries. The keyword here being NEW, because if it's old, all you'll get is a smelly, acrid, smoldering pulp of lithium oxide(Li₂O) out of it. You should then remove the plastic cover off the battery. Follow this by cutting the metal casing off the battery. Now, You'll need to hurry with this, becuase if you short the battery, which you will, the lithium will start to burn up. To alleviate the burning, just remove the moisture/ oxygen source (ie. cover it with a towel for a few seconds). Finally, pull out the lithium with pliers or with gloved hands and place in an air tight, moisture-free container.

     Now, to ignite, just add water!

Lead And Sulfuric Acid:

     If you ever have a dead car battery lying around, why not get some use out of it's components: Lead plates and sulfuric acid. I won't explain the process that lets lead acid batteries work, for that you can goto http://en.wikipedia.org/wiki/Lead-acid_battery.

     The first step is to remove the sulfuric acid. On the top of the average lead acid battery, there will be two pressure release valves. These can easily be popped off with a screwdriver, but this varies for every model. Pop off the cap on one side and pour out the sulfuric acid into a corrosion resistant glass or plastic conatiner. While the acid is laced with inpurities, its strong none the less; this is why safety is always paramount. You should always wear chemical resistant gloves and clothes, as well as eye protection incase of splash-back. Repeat this process for ther other side, followed by a final check to see if it is completely empty.

     Now that all but trace amounts of sulfuric acid is left, you can start removing the lead plates. The easiest way that I've found to access this lead is, using a hacksaw with the appropriate blade, cut off the plastic shell. Be careful though, because, due to the acid respreading over the lead plates, the seemingly "dead" battery may regain some of it's voltage. The last thing you want is to be unsuspectingly zapped by a car battery (its the amps that kill, not the volts). 

How To Make Rocket Fuel & Smoke Bombs:

 This is a video from Shooting Eggs Production that sums up this article: 

For fire to exist, it will need multiple things. Enough heat for combustion to occur, a source of fuel, and an oxygen source. But when something is burning, only the outer region can normally burn, because it is the only area that has an oxygen source. But, if it were to have it's own source, say an oxidizing powder dispersed throughout, then it could burn just as fast as the heat travels through the material.

     A realitively easy to aquire oxidizing agent is potassium nitrate(KNO3), also known as saltpeter. You may recognize this also as the oxidizing agent from gunpowder, or a fertilizer component. While you can get some potassium nitrate fertilizer and try to purify it, an easier means would be to purchase some stump remover. "Grant's Stump Remover" contains almost pure KNO3, and is easy to purchase at your neighborhood Lowes, Home Depot, or Ace Hardware.

     For our purposes, The fuel souce will just be table top white sugar (sucrose). Both these will needed to be powderized,so I would recommend using a mortar & pestle. They should be mixed in a 65:35(~3:2) ratio, of KNO3 to sugar respectably.

     Once these are mixed, the fun (and dangerous) part begins. To get thise to mix effectively, they will need to be melted together. To do this, place the powdered mixture in an adiquately sized metal pot, and place on a stove top set to LOW. Slowly stir as the sugar melts as it starts to caramelize. It is inparative that if the mixture starts to smoke that you immediately remove it from the heat source. The last thing you will want to happen is for the mixture to all go up in flames at once.

     When it becomes the consistancy and color of peanut butter, pour of onto/into what ever you want to form it/ store it in. make sure this will withstand the heat from the hot mixture. When its dry, enjoy!

These are Some of the things I've done with my batches:
