I checked my gmail just now and came across this.
This was sent by my mom's friend.
I found it's interesting, so I share this with you.
Maybe you can try this at home hehe.. :)
How to seal a plastic 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 never try this before. Maybe i'll try it someday. :)
That's it for now.
Take care. :)
