Tired of tying plastic bags and than having to rip them without ability to reuse them? me too.. but i have a solution for that: bottle recycled bag sealer. It won't cost you anything and will definitely make your life easier. Let's see..
Step 1: Watch Video
Step 2: Materials
You will only need a bottle (which I took from the local recycling stand) and a knife/ scissors.
Step 3: Making
There's no much to do here.. cut around the top of the bottle (carefully) open the cap, thread the bag's head through the bottle's head. Close the cap and that's it, now you have a free recycled bag sealer that will make you able to reuse bags.
