Monday December 10th, 2012 08:41 NurdRage Presents: 3 Cool Things of Science

We demonstrate three cool things in science including silver trees, cold-activated fluorescence and the fiery reaction of sodium chlorate and candy. First, copper wire is placed into a silver nitrate solution. This makes trees of silver crystals grow off the copper due to a redox reaction, but by eye this is extremely hard to see. Under the microscope however you can actually see this happening in real time. And if the conditions are perfectly right, it can grow quite quickly. Second, Dr. Soprano, a colleague of Dr. N. Butyl Lithium, donated 3mg of an interesting chemical called 9,10-dihydroplatinaanthracene-4,4′-di-tert-butyl-2,2′-bipyridine. This chemical, among other things, has the property that it is only fluorescent when solid, not when liquid. So if a non-fluorescent solution is cooled with liquid nitrogen until it freezes, it becomes fluorescent. Third, the classic reaction of sodium chlorate and candy. Molten sodium chlorate instantly ignites flammable materials and the resulting firestorm can be quite dramatic. Normally potassium chlorate is used for this demonstration but we happened to have sodium chlorate on hand. If you have any suggestions for experiments or demonstrations, please comment! Our website

      you sould do the thing where you put a full copper penny in a tray and then put acid im not sure what and it will disappear into gas and then poor in something else and it will reappear as a copper blob

      Hey nurdrage i think this can important for you and other..
      :The relativ atom masses are to handel (addit) with (g/mol=x*10^-36) for the exactly molecularmass, divide it by the number of atoms and verb they paralell to the exactly ratio you want. You can to addit the sames atoms before do the paralell verbs.

      It is a kind of magic sure. sell an periodensystem with relative atommasses and more (study knowledge).

      I like the texas instrument calculators (not the cheapest.)

      can you do something with fluorescent phosphorus? or whatever it’s called where you leave it in the light and it glows green in the dark? and how the glow weakens in the cold and strengthens in the heat? I was wondering if you’d take this to Liquid Nitrogen and close-to-melting-point temperatures and see what happens.
