Flip Straw / Straw

Flip Straw
Flip Straw

We always throw away the straw after drinking sweet drinks, because it's difficult to washed the straw completely, especially the surface which is inside. It's really wasted and not environment-friendly. The material of this straw is softer than the original one, It's a little like the rubber. The top of this upside down straw is a little bigger than the bottom, and there has four holes on the bottom of the straw. We can use a stick which with claws on it to hold the hole and then pull the straw's bottom to the top. The surface which is inside will be change to the outside, so we can wash it completely and use it again and again.
