Strike a Match - Complex Chemistry

The chemistry of lighting a match. If you want to see in a dark room, light a match. It's simple isn't it? Not so fast, it is actually quite complex. A slow motion video at 40,000 frames per second shows the process. The completed video spreads out 0.10 of a second into one and a half minutes. Ignition takes place inside the "live" head of the match. It is just a little explosion followed by "slow" burn. The chemical blob does not burst into pieces. I holds together with small bits rolling to the outside surface.  It looks a planet exploding. The main ingredient of a match head is antimony trisulfide : potassium chlorate makes this burn. Ammonium phosphate is also there to reduce particles from escaping, but some smoke is inevitable. Paraffin wax coats the match down to the halfway mark to ensure the flame continues on down the matchstick. Powdered glass and red phosphate in the strike strip on the side of the matchbox ignites by f...

Some Fish Live in Toxic Acid Water

Biology: Atlantic Molly fish of Mexico survive high hydrogen sulfide acid. There is hope for the future of fish as the world is polluted more every day. Some fish can live in extreme toxic, acidic environments. For example, the Atlantic Molly fish of Mexico can survive high levels of hydrogen sulfide acid. They are the only fish in volcanic freshwater springs. Mollies do not filter out the toxin. They turn on certain genes that do the filtering job for them. Of the fish's 35,000 genes 170 are enhanced in the process: these linked genes are all involved in removing hydrogen sulfide. If things get serious and species of fish begin to die out, this group of genes could be "spliced" into the gene structure of endangered fish. They would not be the same fish, but at least some vestige of the evolutionary sequence of dying fish would live on. ◆ Biology by Ty Buchanan   ◆ Adventure Australia Funny Animal Photos Funny Weird Things Articles News Reviews ● ...
