Chemistry edit

  • Brooker's merocyanine -- better lighting, better colors, higher rez, white background...
  • Exothermic reaction -- Bromine & Red Phosphorus reaction & video, or thermite...
  • Halogen - Chlorine, Bromine and Iodine gases in 3 volumetric flask's on white background to illustrate the colors.
  • Anhydrous & Hydrate - Having an anhydrous chemical like Copper(II) sulfate in a watch glass and drip water in the center to illustrate the color difference between the anhydrous and hydrate version. Like this image in composition except sharp and with a white background. (note I found this image which might be sufficient, but I'd still like to make one on a white background).
  • Mole (unit) - Group of several elements measured out in containers one mole each, to demonstrate how much volume some take up due to density over others. Second image with compounds instead of elements, to demonstrate the extreme differences in volume some compounds have for one mole. (like Sodium Chloride and Calcium Carbonate).
  • Precipitation (chemistry) - Closeup of a beaker demonstrating a very colorful precipitate, lead nitrate and potassium iodide both clear solutions, mix to form a bright yellow lead iodide precipitate. this reaction except a higher technically proficient image, larger reaction with a white background and better lighting. Also Potassium chromate solution (yellow) dripped into Silver nitrate solution (clear) forming a dark opaque red precipitate Silver chromate. Also Sodium chloride is dripped into Silver nitrate forming a white precipitate Silver chloride.
  • Paper chromatography - Image depicting it, possibly with florescent dye mixtures under UV light for more "wow" factor. Time lapse video maybe under UV light as well, maybe.
  • An Alkali metal reacting with water with phenolphthalein indicator, likely Lithium or at most Sodium, shot from above to view the color change of the indicator to illustrate the hydroxide forming. Like this except again higher quality, better lighting, and probably also include good video.
  • Cyanidin - Red cabbage extract, PH Indicator. Series of test tubes/vials with a back light white background showing color change in various household liquids. (1) lemon juice, (2) soda water, (3) 7-Up, (4) vinegar, (5) ammonia, (6) lye (sodium hydroxide), (7), milk of magnesia, (h) detergant in water. Noteing how strong bases (5 & 6) will destroy the dye producing a birhgt yellow instead of the expected blue.
  • Redox - beaker with white background, copper sulfate solution with zinc metal strip half submerged in it. Showing after time the redox reaction, possibly even time lapse. Also Silver Nitrate with copper suspended in it showing that reaction.
  • Titration & Acid-base titration - A less hokey demonstration, video, than this gif and stamp that horrid gif out of use. Good image showing the stoichiometric point as well.

Physics edit

  • Ductility (and Gold Leaf) -- Sample of gold leaf with candle behind it showing that it can be hammered thin enough for light to pass through it.
