LUNAR ECLIPSE STRAW / Industrial design

LUNAR ECLIPSE STRAW
LUNAR ECLIPSE STRAW

When we drink milk-tea with covered plastic bottle, it's always getting shrunken as liquid being sucked less and less. Because of air pressure outside of the bottle is more powerful than inside, we usually use our fingers to make a small hole near the edge where straw meets the bottle. However, it's not clean and milky-tea may be spilt out because of carelessness.
