Check out a video on how to do it, below:
One thing to be very careful about is the use of a Kiwi Coil on a glacier. It is important to add one additional element to tie off the rope. The climber should tie an overhand knot in the line and clip it to a carabiner. The reason one does this is to ensure that if your partner falls into a crevasse and you have to untie the Kiwi, you won't get strangled when it comes undone.
