The Betts lightning rocket

Fellow rocket blogger R2K found this excellent video of model-sized rockets being used to attract/guide lightning strikes. Unlike some other systems, these do not use a guide line but rather expel a calcium chloride solution to create the conductive path.  R2K includes a lengthier description. PS - The last few clips are unrelated and last one is disturbing so I suggest you stop it at 4 minutes in.
