Coaster
 This invention is concerned with a coaster for drinking cups comprising: PA1 a circular wall section; PA1 a base section enclosed within said wall section; PA1 a first rim means projecting upwardly from the base section and extending from the wall section toward the center of the coaster; PA1 a second rim means shorter in length than, but equal in height to, the first rib means, the second rim means projecting upwardly from the base and extending from the wall section towards the center of the coaster; PA1 the first and second rib means positioned so that a cup placed within the coaster may contact the top portion of each upwardly projecting rib means; PA1 the first and second rib means being separated an effective droplet removing distance from each other at a point approximately where both rib means contact the wall section. By appropriately spacing the rib means, condensation droplets that are formed on a drinking cup can conveniently pass from the cup into the coaster.
