A top (also called spinning top or spintop) is a toy that can be spun on an axis, balancing on a point. This motion is produced in the most simple forms of top by twirling the stem using the fingers. More sophisticated tops are spun by holding the axis firmly while pulling a string or twisting a stick or pushing an auger as shown in the pictures on this page. In the kinds with an auger, an internal weight rotates, producing an overall circular motion.
The top is one of the oldest recognizable toys found on archaeological sites. Spinning tops originated independently in cultures all over the world. Besides toys, tops have also historically been used for gambling and prophecy. Some role-playing gamers still use tops to augment dice in generating randomized results; it is in this case referred to as a spinner.[citation needed] A thumbtack may also be made to spin on the same principles.
The action of a top relies on the gyroscopic effect for its operation. Typically the top will at first wobble until the shape of the tip and its interaction with the surface force it upright. After spinning upright for an extended period, the angular momentum, and therefore the gyroscopic effect will gradually lessen, leading to ever increasing precession, finally causing the top to topple in a frequently violent last thrash.
A lake is a body of relatively still fresh or salt water of considerable size, localized in a basin, that is surrounded by land apart from a river, stream, or other form of moving water that serves to feed or drain the lake. Lakes are inland and not part of the ocean and therefore are distinct from lagoons, and are larger and deeper than ponds. Lakes can be contrasted with rivers or streams, which are usually flowing. However most lakes are fed and drained by rivers and streams.
Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers. In some parts of the world there are many lakes because of chaotic drainage patterns left over from the last Ice Age. All lakes are temporary over geologic time scales, as they will slowly fill in with sediments or spill out of the basin containing them.
Many lakes are artificial and are constructed for industrial or agricultural use, for hydro-electric power generation or domestic water supply, or for aesthetic or recreational purposes.
Hey you
Over there
Won't you help a stranger
That's a sorry sight my friend
It's not me
To make a fuss
It's just that the water's cold
And i can't feel my legs
Help me out
Don't let me drown in here
Can't you see
I'm gonna die in here
Please excuse
That outburst
I'm a little scared
I don't know what came over me
What's wrong
Don't close your eyes
I don't want to hurt you
I just need a little help
Help me out
Don't let me drown in here
Can't you see
I'm gonna die in here
Swim he says
Why do you say these things
One last chance
