Smoostraw / drinking straw


In our daily life when we have a cup of drink, we stick the straw through the cover of the cup. However, since the straw is equally thick at both ends, the straw itself blocks the only passage throughout the cup, therefore the air from outside can hardly come into the cup as we suck the straw, thus we have to exert more strength and the cup shrinks.
Smoostraw provides a simple solution to this problem. Since the inside end of Smoostraw is thicker than the outside one, there will be a gap between the straw and the cover of the cup after we stick the straw in. Thus the air comes in through the gap and we can enjoy the drink smoothly.
