Carry Liquids On A Plane In 2-Liter Bottles

“Baby Soda Bottles” are 2-liter bottles before they’ve been heated and formed into their soda bottle shape. In this pre-bottle stage, they make waterproof, hard-to-crush containers for small objects, and they hold approximately 2 ounces of liquid which makes them useful for air travel. Oh also, you can use regular 2-liter bottle caps on them.
