Ana's+Grain+Elevator+Explosion

**Materials: ** > **Procedure: ** > 1. Take the funnel and put it in the can so the thinner end of the funnel is poking out of the outside hole.  > 2. Then take Lycopodium powder and put in the end of the tube. After that, take the tube and stick it in the thinner end of the funnel. > 3. Now take a match and lit the small candle. > 4. Then, take the candle and carefully put it inside the tin can. > > 5. After that, blow at the other end of the tube which will cause the Lycopodium powder to disperse into the flame of the candle and cause an explosion. > > > **Explanation: ** > **Lycopodium powder is a yellow powder from spores of //Lycopodium clavatum// ****which is a horn club moss or running ground pine. When a pile of Lycopodium powder is on a table and a lighted match is drop on top of it, the powder does not burn (not much surface area). However, when the powder dispersed into a flame of a candle, then an explosion occurs. This explosion is called a combustion reaction. A combustion reaction is a chemical reaction between a fuel and oxygen which produces heat (could be light) and water. This results into a combustion reaction because when the powder is dispersed into the flame, the available surface area is increased and the Lycopodium powder particles are surrounded by enough oxygen to cause a reaction. Surface area is the measurement of exposure (in this case) of oxygen for Lycopodium powder. ** > > **Equations involved: ** > Fuel (ex: Lycopodium powder) + Oxygen (O2)→ Carbon dioxide (heat) + Water vapor  =combustion reaction

 * <span style="color: #3cd6de; font-family: 'Arial','sans-serif'; font-size: 9pt; mso-bidi-font-size: 12.0pt;">Grain elevators are buildings for storage of grain. They were invented in 1842-1843 by a local merchant named Joseph Dart and an engineer named Robert Dunbar in Buffalo, New York. **
 * <span style="color: #3cd6de; font-family: 'Arial','sans-serif'; font-size: 9pt; mso-bidi-font-size: 12.0pt;">Grain elevators were constructed of wood before and had a greater chance to cause a fire, but now they are constructed of steel or concrete. **
 * <span style="color: #3cd6de; font-family: 'Arial','sans-serif'; font-size: 9pt; mso-bidi-font-size: 12.0pt;">There 950 species of Lycopodium with 37 of them in temperate and tropical climates. **
 * <span style="color: #3cd6de; font-family: 'Arial','sans-serif'; font-size: 9pt; mso-bidi-font-size: 12.0pt;">Lycopodium is a plant that has been used medicinally since the middle ages for digestive disorder, kidney stones, and water retention. The spores of the Lycopodium powder are also used in fireworks. **

You can also understand other chemical reactions. <span style="color: #a7f207; font-family: 'Arial','sans-serif'; font-size: 9pt;"> On April 3, 2008 there were many incidents of combustion reactions of grain elevators. On Thursday at 2:00 PM a combustible dust fired of titanium dust at a dental equipment manufacturing facility in Pennsylvania. In the Midwest at 2:30 PM. The same titanium dust flamed at the Den-Tal-Ez Inc dental facility in Lancaster. Then another combustible dust explosion happened at the Farmer’s Co-op Society grain elevator in Sanborn, Iowa. After that, an hour and a half later the Baldwin Feed and Seed grain elevator exploded in Bladwin, Wisconsin.
