Go to Lowe's or Home Depot and get several feet of the plastic (or plastic-like) tubing that's used for the water supply line to a refrigerator or icemaker, and cut it to desired lengths. Be sure to wash it good before use.
They have the narrow tubing (1/4" O.D.) that works well for hot liquids that you sip and the wider tubing (1/2" O.D.) for those bevs you really want to suck down. 73 Greg K4KO Lebanon, TN Attend the Tennessee QSO Party www.tnqp.org .
