Subject: How to Re-Use Plastic Bottle Tops and Caps
The guy who first thought of the idea must be given an award for originality!!! What a fantastic idea!
How to seal a bag and make it air-tight!
Cut up a disposable water bottle and keep the neck and top, as in photo.
Insert the plastic bag through the neck, and screw the top - to seal.
The bottle is made to be air-tight, such that water will not leak. The secret lies with the top and screw! This is a great idea to share. Good for us, and the environment too.
I'd say this subject is airtight! - Myra 8-)
