PURPOSE: A straw containing a propeller is provided to cool hot drink, to enable a user to enjoy carbonic acid of carbonated drink, and to mix contents of drink well. CONSTITUTION: A straw containing a propeller comprises: a wide space(10) formed in a specific site of a straw; and a propeller(20) which is built in the space in order to cool drink. The temperature of drink is lowered since the propeller rotates by using liquid coming up through the straw when a user sucks in drink. The straw is made of a transparent material, thereby the rotating propeller can be seen from the outside. |
