On my darkroom door I had a sign which warned people, "Shut the door or the dark will leak out." I'm amazed you were able to keep it in there at all. I once spent several nights capturing about half a pint of darkness in a jam jar, which I then sealed up tight – even using gaffer tape round the lid. But no matter what precautions I took, by morning it had always escaped.

[adam]Well there's your problem[/adam] Dark is only restrained by opaque containers, obviously a transparent jam jar won't work. In Canada, we cover silicone the lid on, then wrap duct tape completely around ALL sides of the jar - including top and bottom. (Remember to do this in a dark room of course, so it can be tricky) The dark won't escape at all. Try it. Now, when you remove any of the duct tape it will start escaping, so don't do that. Instead, label the jar with a magic marker, "Contains Darkness - DO NOT TAMPER WITH", and you will be fine. I'm glad that I have some useful information to put up on this forum. EDIT: Oh, hear are some instructions based on a recent Disinfo Agent pack: EDIT AGAIN: Actually, there is a way of verifying that you have captured the Darkness. Its rather technical, but basically you reverse everything you've done, and then look in the jar in a completely dark room. If you don't see anything, then it's still there. Be careful not to spill it out. Maybe Jay can provide the particulars of this method in detail. ;D

Use the Swoosh Method.The trick is to get the lid on the jar before the darkness escapes, but this method is rated for a 95% jar fill rate by my reckoning. Just use a steady motion - not too fast or slow. If you guys really want something challenging, try to do it without filling getting air into the jar. Yes, I mean Pure Darkness, not Atmospheric Darkness that we are all used to. Now, that would be a neat thing to do...

Dark is only restrained by opaque containers, obviously a transparent jam jar won't work. Thanks for the advice, but I'm really not so sure: I did try it with an opaque container, but wasn't able to tell if I'd caught it. When I peeked inside with a torch to check, it had escaped already. At least with a clear jam jar you can see you've caught it.

Use the Swoosh Method.I use a similar method for capturing silence from the top of Scotland.
