Using Plastic Bottles to seal plastic bags.

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 bag is made to be air-tight, such that water will not leak, the
secret lies with the top and screw cap!  This is a great idea to share.

Good for us and the environment too.

Zip-top bags are great, but sometimes you buy something in bulk and you're stuck with an unsealable bag. Home-centric blog Re-Nest shows us an easy way to give these bags an airtight seal with an old water bottle.

All you need to do is cut off the top of the bottle and take off the cap. Push the bag through the bottle neck, fold it over the edges, and twist the cap back on. Now, your bag has an air and water tight seal, and you didn't have to waste the bag.

This was an e-mail sent to me by a friend.  I often wish I were clever enough to think up something so brilliant.
