Tongue Twisters an expression that is difficult to articulate clearly; "`rubber baby buggy bumper' is a tongue twister". Here at TongieTwisters.us, we have collected and organized all short, hard, funny and difficult or the hardest of the tongue twisters from all over the web. If you have a tongue twisters that is not there on our site, please contribute it so that we can share it with the other visitors here. We plan to keep adding until this site is the #1 resource for tongue twisters online! Help us do that and contribute any tongue twisters you may have, short or long, funny or not funny, we will take them all :).

Every day I work as a production planner and forcing a full day in front of a computer with lots of files on the desk. Indeed the situation is often made less fresh mind, how to keep the table clean, but work remains to be done. How to use two common office supplies to make a supper-office supply, with the help of simple tools such as file clips eventually I became a neat desk and work equipment is easy to find.

Some people think that to have the desired house needed substantial capital investment. But smart people different point of view, they can utilize existing facilities in the form of soft loans from several agencies home loan provider. If you're in financial trouble to buy a house, renovating or building a house, it helps you read the information on this mortgage.

Various lucrative offers to be there, but take your time, learn it well, calculate profits and adjust with the ability to hurt you, do not let your salary is only used to repay the home, set up only one third of your salary is allocated to repay the loans, so that you could still enjoy life, without being overly burdened with mortgages.

I hope you happy with your new home.

In a laboratory a condenser is a piece of laboratory glassware used to cool hot vapors or liquids. A condenser usually consists of a large glass tube containing a smaller glass tube running its entire length, within which the hot fluids pass.

The ends of the inner glass tube are usually fitted with ground glass joints which are easily fitted with other glassware. The upper end is usually left open to the atmosphere, or vented through a bubbler, or a drying tube to prevent the ingress of water or oxygen.

The outer glass tube usually has two hose connections, and a coolant (usually tap water or chilled water/anti-freeze mixture) is passed through it. For maximum efficiency, the cold water always enters through the bottom fitting, and exits through the top fitting. Multiple condensers may be connected in series. Normally a high flow rate is not necessary to maintain a cooling surface.

Condensers are often used in reflux, where the hot solvent vapors of a liquid being heated are cooled and allowed to drip back. This reduces the loss of solvent allowing the mixture to be heated for extended periods.

Condensers are used in distillation to cool the hot vapors, condensing them into liquid for separate collection. For fractional distillation, an air or Vigreux condenser is usually used to slow the rate at which the hot vapors rise, giving a better separation between the different components in the distillate.

For microscale distillation, there are commercially available apparatus which include the "pot", and the condenser fused into one-piece. This reduces the hold-up volume, and obviates the need for ground glass joints preventing contamination by grease and air leaks.

A common spatula design

A turner (in British English), or fish slice, is a kitchen utensil with a long handle and a broad flat edge, used for lifting fried foods.[1][2] Though the word spatula is used in British English, it refers solely to a mixing and spreading implement.[3] Often the plate scraper is referred to as a spatula. In some parts of Scotland (e.g. Glasgow or Victoria Halls[citation needed]) the spatula is also known as a tosser which refers to the tossing of omelettes or pancakes.

The word spatula, known in English since 1525, is a diminutive form of the Latin term spatha, which means a broad sword (as in spatharius) or a flat piece of wood and is also the origin of the words spade (digging tool) and spathe.[4]

Spatulas have a handle that is long enough to keep the holder's hand away from what is being lifted, flipped, or scraped. The blade is usually somewhat flexible, and shiny. Spatula blades are often longer on the right side than the left, as this is more effective for right-handed people. There are also left-handed spatulas, but these are rare. Most have long slots on the blades to allow liquids to flow through, though some have holes or no perforations at all.

Spatulas are usually made of plastic or metal, with a wooden or plastic handle to insulate them from heat. Spatulas made for outdoor grilling have very long handles.

Spatulas can be colorful or have artistic designs. They can be used as decorations in the home or used in some abstract art forms.
