I came up with this while packing for school and getting frustrated with the cargo limitations of my car's trunk. This makes packing for college much less stressful as space becomes much less of a constraint by compacting large items such as comforters, bedding, and clothes.
Step 1: What You Need
-Vacuum cleaner with a hose
I used drawstring kitchen bags, but large black garbage bags would work very well, as they are less prone to tearing.
Step 2: Fill a Bag
Step 3: Hold the Bag Closed
Step 4: Insert Vacuum and Suck!
Step 5: Tie the Bag Shut
Step 6: Unpacking
When the time comes to restore all your stuff to its air-filled glory, just open the bag and watch your stuff spring back to life!
Step 7: Troubleshooting
If the bag fails to shrink:
-Make sure the bag has no holes
-Make sure that your hand has formed a complete seal around the vacuum
-Maneuver the vacuum so it isn't sucking in the side of the bag. It helps to place the vacuum against whatever you are packing.
