What is claimed is:

1) A material sampling device comprising: a) an auger, wherein the auger comprises an auger blade and an auger shaft, wherein the auger is configured to extract material from a container, thereby creating a primary material sample; b) a first motor, wherein the auger motor is in mechanical communication with the auger shaft, wherein the first motor is configured to rotate the auger; and c) a rotatable tube assembly, wherein the rotatable tube assembly comprises i) an outer tube, wherein the outer tube is configured to house at least a portion of the auger, wherein the outer tube is configured to allow the auger to rotate within the outer tube, wherein the outer tube comprises a lower portion, wherein the lower portion is configured to rotate, and ii) a second motor, wherein the second motor is in mechanical communication with the lower portion of the outer tube, wherein the second motor is configured to rotate the lower portion of the outer tube.

2) The device of claim 1, wherein the outer tube further comprises an upper portion, wherein the upper portion is configured to remain stationary.

3) The device of claim 1, wherein the outer tube further comprises a bit head, wherein the bit head is positioned on a bottom end of the lower portion of the outer tube, wherein the bit head comprises a bottom edge and at least one tooth, wherein the at least one tooth projects downward from the bottom edge, wherein the at least one tooth is configured to facilitate movement of the device through material.

4) The device of claim 3, wherein the bit head is integral with the lower portion of outer tube.

5) The device of claim 3, wherein the bit head comprises a discrete component, wherein the bit head is fixedly attached to the lower portion of the outer tube.

6) The device of claim 1 , wherein the second motor is configured to produce multidirectional rotation of the lower portion of the outer tube.

7) The device of claim 1, wherein the first motor is configured to produce rotation of the auger in a first direction, wherein the second motor is configured to produce rotation of the lower portion of the outer tube in a second direction, wherein the first direction is substantially opposite the second direction, wherein the rotation of the auger in the first direction and the rotation of the lower portion of the outer tube in the second direction occur substantially simultaneously.

8) The device of claim 7, wherein the second motor is further configured to produce rotation of the lower portion of the outer tube in the first direction.

9) The device of claim 1, wherein the rotatable tube assembly further comprises: a) a first gear, wherein the gear is in mechanical communication with the second motor; and b) a turntable bearing, wherein the turntable bearing comprises a circumferential gear, wherein the circumferential gear is in mechanical communication with the first gear, wherein the turntable bearing is further in mechanical communication with the lower portion of outer tube, wherein rotation produced by the second motor is communicated to the lower portion of the outer tube via the first gear, the circumferential gear and the turntable bearing.

10) The device of claim 1, wherein the primary material sample is conveyed by the auger upward through the outer tube, wherein the outer tube further comprises an outlet through the primary material sample is moved, the device further comprising: a) an integral material separator, wherein the material separator is configured to separate the primary material sample received from the outlet of the outer tube, wherein the material separator comprises a first window, through which a portion of said primary material sample is directed, thereby creating a secondary material sample that automatically passes through the first window via gravity, wherein the material separator further comprises a second window in communication with a discharge shaft that is open at its bottom portion, thereby providing an opening through which the remaining portion of the primary material sample automatically passes via gravity; b) a material crusher, wherein the material crusher is configured to crush the secondary material sample that passes through the first window into particles small enough for useful analysis thereby creating a crushed material sample, wherein the material crusher further comprises at least one outlet; and c) a material collector, wherein the material collector is configured to collect the crushed material sample received from the at least one outlet of the material crusher, for analysis.

H) A coal sampling device comprising: a) an auger, wherein the auger comprises an auger blade and an auger shaft, wherein the auger is configured to extract coal from a container, wherein the auger is configured to rotate; and b) a rotatable tube assembly, wherein the rotatable tube assembly comprises an outer tube, wherein the outer tube is configured to house the auger blade and at least a portion of the auger shaft, wherein the outer tube is configured to allow the auger to rotate within the outer tube, wherein the outer tube comprises a lower portion, wherein the lower portion is configured to rotate; wherein the auger and the lower portion of the outer tube are configured to rotate simultaneously in opposite directions.

12) The device of claim 11, wherein the outer tube further comprises an upper portion, wherein the upper portion is configured to remain stationary.

13) The device of claim 11, wherein the auger and the lower portion of the outer tube are further configured to rotate simultaneously in the same direction.

14) The device of claim 11, wherein the auger is configured to rotate independently of the lower portion of the outer tube, such that the auger is configured to rotate while the lower portion of the outer tube remains stationary and the lower portion of the outer tube is configured to rotate while the auger remains stationary.

15) The device of claim 11, wherein the outer tube comprises an outer surface having a length and a circumference, wherein the outer surface is substantially continuous along substantially the entire length of the outer surface, wherein the outer surface is substantially continuous across substantially the entire circumference of the outer surface.

16) The device of claim 11 , wherein the outer tube further comprises an outer surface and a plurality of external features along the outer surface, wherein the external features are configured to facilitate movement of the device through the coal.

17) The device of claim 16, wherein the plurality of external features are selected from the group consisting of teeth, spirals, projections, and protuberances.

18) The device of claim 11, wherein the outer tube further comprises a bit head positioned on a bottom end of the lower portion of the outer tube, wherein the bit head further comprises an interior surface and a plurality of internal features, wherein the internal features are positioned along the interior surface of the bit head, wherein the internal features are configured to facilitate movement of the device through the coal.

19) The device of claim 18, wherein the internal features are selected from the group consisting of teeth, spirals, projections, and protuberances.

20) A method of sampling material comprising the steps of: a) providing a material sampling device, wherein the material sampling device comprises i) an auger, wherein the auger is configured to extract material from a container, wherein the auger is configured to rotate; and ii) a rotatable tube assembly, wherein the rotatable tube assembly comprises (1) an outer tube, wherein the outer tube is configured to house at least a portion of the auger, wherein the outer tube is configured to allow the auger to rotate within the outer tube, wherein the outer tube comprises
