These instructions will guide you step by step through the process of making a very effective jar lid filter that will allow for fast colonization of shakeable substrates through better gas exchange without compromising their sterility.

Required materials:

Where can you get it? At Ebay (links above) you should easily find it.
Offline you get it at craft stores like Michaels or the craft section of Meijers or Walmart, when you ask at Walmart in arts and crafts department tell them that you are looking for pillow filling or batting.
It's also used as filter material for aquariums("polyester filter floss"), thus aquarium and pet shops have it.

Screw the lid on the jar and punch a hole in the lid using the screwdriver and the hammer.

Take some floss and fold it to a small ball using both hands.

Make the ball having a tip at one end.

Put this end through the hole and pull it app. halfway through. It should form a relatively tight seat.

Be careful not to cut yourself on the sharp edges!

Push the floss back towards the edges. This will hold it in place.

Ready.
You should replace the filter floss after using it 3-4 times just to make sure no substrate residuals collect on it which could support growth of contaminants.
