The folks over at the blog for a self-setting rubber product called sugru have been busy finding new and ingenious ways to use sugru, like this clever LEGO cable and key holder.
sugru can be formed and shaped by hand for up to 30 minutes once it has been removed from its packaging. sugru is like modeling clay when you take it from its pack. Once it's exposed to air, it cures to a tough flexible silicone overnight using the moisture in the air. Working time = 30 mins. Cure time = 24hrs (3-5 mm deep)
