    [–] Gravitational pull on soapy water IHaeTypos 30 points ago in physicsgifs

    From the source:

    A thin film of soapy water that is vertically suspended across a 19 cm diameter plastic ring and illuminated with white light. Gravity pulls down on the film to make it much thinner in the top section of the ring than in the bottom section. Light reflecting from the front surface of the thin film is able to interfere with light reflecting off of the back, resulting in different reflected colors from different film thicknesses.

    [–] Reduction of Potassium Permanganate into Manganese Dioxide IHaeTypos 9 points ago in chemicalreactiongifs

    From the source:

    The chemical chameleon is a series of reactions of reduction of potassium permanganate into potassium manganate and into manganese dioxide sequentially.

    I will mix potassium permanganate with an aqueous solution of sugar and sodium hydroxide. Each one of the resultant products has a different color.

    [–] Toluene + Sulfur crystallization IHaeTypos 57 points ago in chemicalreactiongifs

    The flask is filled with 10 grams of crushed sulfur. 100ml of Toluene is poured in, and the flask is heated up on a stove, and the sulfur begins to dissolve. When the mixture reaches 95 degrees Celsius, the sulfur is completely dissolved. The mixture is left to cool, and upon reaching 55 degrees Celsius, yellow needle crystals of Sulfur are created. If the mixture is heated again, the crystals will dissolve and the experiment can be repeated.
