1. Insert deflated balloon in bottle.
2. Inflate balloon as much as possible until soda doesn't rise anymore.
3. Put a twist tie on the end. No need to cap.
I think this would work. But I haven't tested it in the field.
OR: (If you are near a water source)
1. Insert deflated balloon in bottle.
2. Fill balloon with water.
3. Put a twist tie on the end. No need to cap.
All we are trying to do is replace the missing volume of liquid (and hence pressure) from the bottle, right? So it doesn't NEED to be a gas we are using, right?
Keep in mind I'm bad at basic science.
I always said soda should come in toothpaste-like tubes so you can squeeze it and force the soda to be in a smaller area to the top as you go. The interior of the tube could be lined with a substance that uses the Van der Waals force so it stays joined after you squeeze.
Okay...patent time.
