Warning: Thionyl chloride is one of the only easily obtainable chemicals that rates a 4--Extreme Risk on the NFPA diamond for health. Do not bring it in the house in anything but a strong, sealed container. Noxious fumes are created in this experiment.
You will need:
Lithium-thionyl chloride battery (I obtained mine from an EZpass device in the woods)
Water
Drill
Pliers
Very very sealed container
Remove as much from the lithium-thionyl chloride battery as you can. These things are built very strongly so a drill is needed. After you remove all the extra stuff from the battery, you should see a carbon rod sticking out on one side. Drill it out. As you drill, you will see smoke and smell sulfur. This is the thionyl chloride around the carbon rod reacting wih the water in the air; it is not fire. After a nice hole is drilled, remove your smoking drill bit. Then, place the battery hole down in the sealed container and let the thionyl chloride drip out. The container may cloud up. You may have to squeeze the battery to get significant amounts of thionyl chloride out. Now you have thionyl chloride. It can be used for producing the anhydrous forms of several metal compounds. It also reacts vigorously with water. Place a drop of it in water. Bubbles of sulfur dioxide will leave, along with some HCl fumes. Both of these gases are very annoying to the nasal passages. Do what you want with the rest of the thionyl chloride.
