Drinking Straw Pops Out When Bottle Is Opened (Apr, 1939)
Drinking Straw Pops Out When Bottle Is Opened
Don’t be surprised, when you open a bottle of your favorite soft drink, if a clean, sanitary straw pops out of the beverage. It’s the latest wrinkle in bottling and may make a fortune for its clever inventor. Inserted when the bottle is capped, the waterproof straw is closed at the top, trapping air that makes it buoyant. For use, you simply pinch the top to open it, and extend the telescoping straw so that it will be long enough to reach the bottom of the bottle.
