I swapped one of the rings with the ring from my key chain, which is a slightly smaller diameter so it fits inside. That way the two rings only take up the same amount of space as the larger ring would by itself. I've considered hollowing out the top part of my tealight candle so that the split rings would actually fit inside it - I think the impact to the candle's usefulness would be negligible, (although I understand that a lot of people here don't have a high opinion of the usefulness of a tealight in the first place, anyway <img src="images/graemlins/smile.gif" alt="" /> ) Of course, I still have the original ring on my keychain if I need it, but if I don't have time to remove the keys from the ignition before the car sinks in 14 feet of ice water, then I'd rather have a self-sufficient PSK in my pocket <img src="images/graemlins/wink.gif" alt="" />
