Dust Explosion (Interactive)
In these videos adapted from the Journal of Chemical Education, learn about the dangers of grain elevators and observe the combustion of lycopodium powder. The demonstrator places fine particles of lycopodium powder into a funnel inside a container that also holds a lit candle. Air is forced through the funnel, causing the powder to disperse within the container, and then resulting in an explosive chemical reaction. This demonstration illustrates the hazard of dust explosions—specifically,

Global Lightning Flash Rate Density (WMS)
Lightning is a brief but intense electrical discharge between positive and negative regions of a thunderstorm. The Lightning Imaging Sensor (LIS) on the Tropical Rainfall Measuring Mission (TRMM) satellite was designed to study the distribution and variability of total lightning on a global basis. The Optical Transient Detector (OTD) was an earlier lightning detector flying aboard the Microlab-1 spacecraft. The data shown here are compiled from LIS (1998-2002) and OTD (1995-1999) observations.

Testing the waters
Chemistry professor John Brennan talks about a paper strip, developed at McMaster University, that can detect harmful concentrations of E. coli in recreational water within minutes. The bioactive paper detects E. coli quickly* and simply, with much greater accuracy than existing portable technology. Read the full story: http://dailynews.mcmaster.ca/story.cfm?id=8902 *Test time accelerated for video demonstration.
Energy in a Roller Coaster Ride

DNA Extraction (Interactive)
In this interactive activity adapted from the University of Nebraska's Plant and Soil Science eLibrary, learn how DNA is extracted from leaf tissue for molecular techniques, such as PCR. As the animated sequence shows, DNA extraction involves collecting cells, physically breaking them open to release DNA from the nuclei, separating the DNA from other cellular components, and precipitating DNA out of solution for final extraction. The process utilizes basic laboratory tools, such as microfuge tub
