A bright idea

Someone thought  of this and I got this in my inbox yesterday.  The person who thought of this should be given credit for the ingenuity.

Sealing plastic bags with bottle caps.

I think it's worth a try.

Cut up a disposable bottle and keep the neck and top.

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 the screw cap.
