In the experiment, a film canister is filled with water, an effervescent tablet (commonly Alka-Seltzer) is added and the canister tightly sealed. After a short time, the pressure of the carbon dioxide is great enough to cause the body of the canister to be launched into the air with a popping sound. The canister may be embellished with paper ...
The iodine clock reaction is a classical chemical clock demonstration experiment to display chemical kinetics in action; it was discovered by Hans Heinrich Landolt in 1886. [1] The iodine clock reaction exists in several variations, which each involve iodine species ( iodide ion, free iodine, or iodate ion) and redox reagents in the presence of ...
The vinegar is created over the course of 13 years. [2] Mother of vinegar can also form in store-bought vinegar if there is some residual sugar, leftover yeast and bacteria and/or alcohol contained in the vinegar. This is more common in unpasteurized vinegar, since the pasteurization might not stabilize the process completely. While not ...
Flour Babies is a day school novel for young adults, written by Anne Fine and published by Hamilton in 1992. It features a group "science experiment" in a classroom full of underachieving students: "When his class of underachievers is assigned to spend three torturous weeks taking care of their own "babies" in the form of bags of flour, Simon makes amazing discoveries about himself while ...
Turbatrix aceti (vinegar eels, vinegar nematode, Anguillula aceti) are free-living nematodes that feed on a microbial culture called mother of vinegar (used to create vinegar) and may be found in unfiltered vinegar. They were discovered by Pierre Borel in 1656. [1]

"Glacial acetic acid" is a name for water-free acetic acid. Similar to the German name "Eisessig" ("ice vinegar"), the name comes from the solid ice-like crystals that form with agitation, slightly below room temperature at 16.6 °C (61.9 °F). Acetic acid can never be truly water-free in an atmosphere that contains water, so the presence of 0. ...
Hooke ran a bow along the edge of a glass plate covered with flour, and saw the nodal patterns emerge. [ 3 ] The German musician and physicist Ernst Chladni noticed in the eighteenth century that the modes of vibration of a membrane or a plate can be observed by sprinkling the vibrating surface with a fine dust (e.g., lycopodium powder , flour ...
