This is Aurora Tang's method of sealing up her balloons. I think its the best I've seen. It was developed during a project to document Robert Smithson's Spiral Jetty with the Getty Institute. She has used it extensively for landscape photography.

using a knot to trigger cameras
January 29th, 2012 by mathew
This is for use with the PET Bottle Rig
Instead of using a balled up piece of tape, a pebble, or some other thing to hold down my camera's shutter, I've gone to using a knot. This makes it easy to hold in place, and makes setting it easier. I prefer a rubber band, but tape also holds it down. tape may be more useful for bulging, non rectangular cameras.
