What is claimed is: 1. A straw comprising: an outer tubular member having a closed bottom end and at least one aperture through a lower portion of a side wall thereof; an inner tubular member longer than said outer tubular member and having a lower portion of diameter defining an annulus between said inner and outer tubular members, said inner tubular member having an upper portion of outer diameter reciprocally slidable in abutment within an upper portion of said outer tubular member between a full-closed condition with an open bottom end of said inner tubular member seated on said closed bottom end of said outer tubular member and a full-opened condition with said open bottom end of said inner tubular member above an uppermost of said at least one aperture; a first pair of tapered surfaces, said first pair having one of said surfaces on an inner wall of said outer tubular member and another of said surfaces on an outer wall of said inner tubular member, said pair of tapered surfaces mating not lower than above an uppermost of said at least one aperture of said outer tubular member and providing a concentric space in said annulus; and a second pair of tapered surfaces, said second pair having one of said surfaces on an outer wall of said outer tubular member and another of said surfaces on an inner sidewall of a cap for covering and uncovering an open top end of said inner tubular member, said second pair of tapered surfaces mating at an upper end of said outer tubular member, whereby said upper end of said outer tubular member is squeezed by said pairs of tapers in said fully-closed condition. 2. A straw according to claim 1, said closed bottom end of said outer tubular member having a dome-like protrusion extending upwardly therefrom for at least partial insertion into said open bottom end of said inner tubular, said protrusion and said open bottom end mating to provide a seal against flow of liquid into said open bottom end in said fully-closed condition. 3. A straw according to claim 1, said sealing means further comprising another pair of tapered surfaces, said another pair having one of said surfaces on an inner wall of said outer tubular member and another of said surfaces on an outer wall of said inner tubular member, said another pair of tapered surfaces mating proximate an upper end of said outer tubular member. 4. A straw according to claim 1 further comprising means for preventing withdrawal of said inner tubular member beyond a predetermined limit. 5. A straw according to claim 4, said means for preventing withdrawal comprising: an annular groove in an inner wall of said outer tubular member; and a ring of flexible radial tabs extending inwardly from a circumferential wall of said annular groove into flapping contact with an outer wall of said inner tubular member in response to reciprocal motion of said inner tubular member in said outer tubular member. 6. A straw according to claim 5, said means for preventing withdrawal further comprising an annular slot in an outer wall of said inner tubular member for receiving said tabs when said annular slot and said annular groove are aligned, said tabs having upper surfaces which abut an upper surface of said annular groove to prohibit disengagement of said tabs from said annular slot. 7. A straw according to claim 1 further comprising means for sealing an annulus between said inner wall of said outer tubular member and said outer wall of said inner tubular member against flow of liquid therethrough when said bottom of said inner tubular member is spaced above said bottom of said outer tubular member. 8. A straw according to claim 7, said means for sealing comprising an annular bead on at least one of an outer wall of said inner tubular member and an inner wall of said outer tubular member. 9. A straw according to claim 1 further comprising means for covering and uncovering an open top end of said inner tubular member. 10. A straw according to claim 9, said means for covering and uncovering comprising: means for plugging said open top end of said inner tubular member; and means for engaging and disengaging said means for plugging to and from a top end of said outer tubular member. 11. A straw according to claim 10, said means for engaging and disengaging drawing said means for plugging said open top end of said inner tubular member and said closed bottom end of said outer tubular member toward each other during engagement to simultaneously seal said open top and bottom ends of said inner tubular member in said fully-closed condition. 12. A straw according to claim 9, said means for covering and uncovering comprising: a cap having a top and sidewalls; a plug in said top of said cap for insertion into said open top end of said inner tubular member; and complementary threads on an inside of said cap sidewalls and an outside of said outer tubular member for drawing said cap plug and said closed bottom end of said outer tubular member toward each other during tightening rotation of said threads to simultaneously seal said open top and bottom ends of said inner tubular member in said fully-closed condition. 13. A straw according to claim 12 further comprising an annular flange around said outer tubular member and below said cap in said fully-closed condition. 14. A straw according to claim 12, said straw further comprising means on abutting surfaces of said tubular members for sealing an annulus therebetween against flow of liquid therethrough when said bottom of said inner tubular member is seated on said bottom of said outer tubular member. 15. A straw according to claim 14 further comprising a tether connected between said cap and said annular flange. 16. A straw comprising: an outer tubular member having a closed bottom end and at least one aperture through a lower portion of a side wall thereof; an inner tubular member longer than said outer tubular member, said inner tubular member having an upper portion of outer diameter reciprocally slidable in abutment within an upper portion of said out tubular member between a fully-closed condition with an open bottom end of said inner tubular member seated on said closed bottom end of said outer tubular member and a fully-opened condition with said open bottom end of said inner tubular member above an uppermost of said at least one aperture; a first pair of tapered surfaces, said first pair having one of said surfaces on an inner wall of said outer tubular member and another of said surfaces on an outer wall of said inner tubular member, said first pair of tapered surfaces mating at an upper end of said inner tubular member; and a second pair of tapered surfaces, said second pair having one of said surfaces on an outer wall of said outer tubular member and another of said surfaces on an inner sidewall of a cap for covering and uncovering an open top end of said inner tubular member, said second pair of tapered surfaces mating at an upper end of said outer tubular member, whereby said upper end of said outer tubular member is squeezed by said second pair of tapers in said fully-closed condition. 17. A straw comprising: an outer tubular member; an inner tubular member longer than said outer tubular member, said inner tubular member being reciprocally slidable in abutment within said outer tubular member; means for sealing an annulus between an inner wall of said outer tubular member and an outer wall of said inner tubular member against flow of liquid therethrough; an annular groove in an inner wall of said outer tubular member; and a ring of flexible radial tabs extending inwardly from a circumferential wall of said annual groove into flapping contact with an outer wall of said inner tubular member in response to reciprocal motion of said inner tubular member in said outer tubular member, said ring of tabs and said annular groove being cooperable to prevent withdrawal of said inner tubular member beyond a predetermined limit. 18. A straw according to claim 17, said means for sealing comprising an annular protrusion on at least one of said inner wall of said outer tubular member and said outer wall of said inner tubular member. 19. A straw according to claim 18, said sealing means further comprising a pair of tapered surfaces, said pair having one of said surfaces on an inner wall of said outer tubular member and another of said surfaces on an outer wall of said inner tubular member, said pair of tapered surfaces mating proximate an upper end of said outer tubular member. 20. A straw according to claim 17, said means for preventing withdrawal further comprising an annular slot in an outer wall of said inner tubular member for receiving said tabs when said annular slot and said annular groove are aligned, said tabs having upper surfaces which abut an upper surface of said annular groove to prohibit disengagement of said tabs from said annular slot. 21. A straw according to claim 18 further comprising means for covering and uncovering an open top end of said inner tubular member. 22. A straw comprising: an outer tubular member having a closed bottom end and at least one aperture through a lower portion of a side wall thereof; an inner tubular member longer than said outer tubular member and having a liquid inlet end and a liquid outlet end, said inner tubular member having an upper portion of outer diameter reciprocally slidable in abutment within an upper portion of said outer tubular member, said inner tubular member being reciprocally slidable between a fully-closed condition with an open liquid inlet end of said inner tubular member seated on said closed bottom end of said outer tubular member and a fully-opened condition with said open liquid inlet end of said inner tubular member raised above said closed bottom end of said outer tubular member and in liquid communication with said at least one aperture; and a pair of tapered surfaces, said pair having one of said surfaces on an outer wall of said outer tubular member and another of said surfaces on an inner sidewall of a cap for covering and uncovering an open top end of said inner tubular member, said pair of tapered surfaces mating at an upper end of said outer tubular member, whereby said upper end of said outer tubular member is squeezed by said pair of tapers in said fully-closed condition. 23. A straw comprising: an outer tubular member having a closed bottom end and at least one aperture through a lower portion of a side wall thereof; an inner tubular member longer than said outer tubular member, said inner tubular member having an upper portion of outer diameter reciprocally slidable in abutment within an upper portion of said outer tubular member between a fully-closed condition with an open bottom end of said inner tubular member seated on said closed bottom end of said outer tubular member and a fully-opened condition with said open bottom end of said inner tubular member above an uppermost of said at least one aperture; and a pair of tapered surfaces having one of said surfaces on an outer wall of said outer tubular member and another of said surfaces on an inner sidewall of a cap for covering and uncovering an open top end of said inner tubular member, said second pair of tapered surfaces mating at an upper end of said outer tubular member, whereby said upper end of said outer tubular member is squeezed by said pair of tapers in said fully-closed condition.
