	Bumping (chemistry) Bumping is a phenomenon in chemistry where homogeneous liquids boiled in a test tube or other container will superheat and, upon nucleation, rapid boiling will expel the liquid from the container. In extreme cases, the container may be broken. Cause Bumping occurs when a liquid is heated or has its pressure reduced very rapidly, typically in smooth, clean glassware. The hardest part of bubble formation is the initial formation of the bubble; once a bubble has formed, it can grow quickly. Because the liquid is typically above its boiling point, when the liquid finally starts to boil, a large vapor bubble is formed that pushes the liquid out of the test tube, typically at high speed. This rapid expulsion of boiling liquid poses a serious hazard to others and oneself in the lab. Furthermore, if a liquid is boiled and cooled back down, the chance of bumping increases on each subsequent boil, because each heating cycle progressively de-gasses the liquid, reducing the number of remaini ...

picture info	Lock Bumping Lock bumping is a lock picking technique for opening a pin tumbler lock using a specially crafted bump key, rapping key or 999 key. A bump key must correspond to the target lock in order to function correctly. History A US patent first appears in 1928 by H. R. Simpson called a rapping key.''High Security Mechanical Locks - An Encyclopaedic Reference'' published by Graham W. Pulford 2007, p. 19 In the 1970s, locksmiths in Denmark shared a technique for knocking on a lock cylinder while applying slight pressure to the back of the lock plug. When the pins would jump the inside of the cylinder, the plug would be able to slide out freely, thus enabling the locksmith to disassemble the lock quickly. The use of a bump key was not introduced until some time later and was first recognized as a potential security problem around 2002–2003 by Klaus Noch, who brought it to the attention of the German media. After further examination of the procedure, a white paper was drafted in 2005 by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Internet Forum An Internet forum, or message board, is an online discussion site where people can hold conversations in the form of posted messages. They differ from chat rooms in that messages are often longer than one line of text, and are at least temporarily archived. Also, depending on the access level of a user or the forum set-up, a posted message might need to be approved by a moderator before it becomes publicly visible. Forums have a specific set of jargon associated with them; example: a single conversation is called a " thread", or ''topic''. A discussion forum is hierarchical or tree-like in structure: a forum can contain a number of subforums, each of which may have several topics. Within a forum's topic, each new discussion started is called a thread and can be replied to by as many people as so wish. Depending on the forum's settings, users can be anonymous or have to register with the forum and then subsequently log in to post messages. On most forums, users do not have to l ...

	Bumping Lake Bumping Lake is a lake and reservoir along the course of the Bumping River, in Yakima County, Washington state, USA. Bumping Lake has also named as "Lake Plehnam" by Preston's Map of Oregon and Washington in the 1850s, and "Tannum Lake" by the United States General Land Office Map of Washington of 1897. The lake is used as a storage reservoir for the Yakima Project, an irrigation project run by the United States Bureau of Reclamation. Although a natural lake, Bumping Lake's capacity and discharge is controlled by Bumping Lake Dam, a high earthfill structure built in 1910 and modified in the 1990s. As a storage reservoir, Bumping Lake's active capacity is .Yakima Project , United States Bureau of Rec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Bumping River The Bumping River is a tributary of the Naches River, in Washington in the United States. It flows down the east side of the Cascade Range, through Wenatchee National Forest and the William O. Douglas Wilderness. From its source at Fish Lake near Crag Mountain, it flows northeast to Bumping Lake, a natural lake enlarged and regulated by Bumping Lake Dam. Below the dam, the Bumping River continues flowing northeast. It is joined by the American River, its main tributary, a few miles above its mouth where it joins the Little Naches River to form the Naches River. Bumping River is part of the Columbia River basin, being a tributary of the Naches River, which is tributary to the Yakima River, which is tributary to the Columbia River. Stockmen said that the river's name was given because during a freshet heavy boulders were carried down the river creating a rumbling vibration as the rocks kept bumping together.
