Drain cleaners usually contain a strong base such as sodium hydroxide that decomposes hair and converts fats into water-soluble products. The reaction is exothermic, releasing heat to soften the fats. Drain cleaners can also contain aluminum, which reacts with sodium hydroxide to produce bubbles of hydrogen gas that help to break up the clog. [11]
The release of hydrogen gas stirs the mixture and improves the interaction between the lye and the materials clogging the drain. It's possible that pressure may build up inside the pipe, causing the hot, caustic solution to spurt out of the drain. Sodium nitrate reacts with hydrogen gas: Na + + NO 3 − + 4H 2 → NaOH + NH 3 + 2H 2 O. This ...
After some time, graphite refractory in contact with aluminium will react to create aluminum carbides (harder and more detrimental inclusions). In aluminium alloy containing magnesium , the magnesium reacts with some refractories to create rather big and hard inclusions similar to spinels.
An enamelled colander. A colander (or cullender) is a kitchen utensil perforated with holes used to strain foods such as pasta or to rinse vegetables. [1] The perforations of the colander allow liquid to drain through while retaining the solids inside.

The Moeller Method uses the whipping motion, described above, and applies it to the 4 basic strokes of drumming, the Full, Up, Down, and Tap strokes. [6] Using a combination of the basic strokes, in the whipping Moeller style it is possible to play extremely quickly with minimal effort, or to introduce a series of accents into a stream of notes with relative ease.
