mailmanscout Posted April 14, 2004 Share Posted April 14, 2004 What is the best lubricant for the space derby? Has anyone tested to see how many bands are best and twisted how many times? Thanks!!! Link to comment Share on other sites More sharing options...
Fat Old Guy Posted April 14, 2004 Share Posted April 14, 2004 When I used to build rubberband powered balsa wood and tissue paper models, the recommended lubricant was green soap and glycerine. Unfortunately, that was 35 years ago and I don't remember the proportions. Link to comment Share on other sites More sharing options...
packsaddle Posted April 14, 2004 Share Posted April 14, 2004 Silicone grease, the kind used on O-rings, stopcocks, and ground glass fittings. Link to comment Share on other sites More sharing options...
