Bubble Wrap Screen

I love this idea for a dividing screen. This bubble wrap is silicon filled, but I want to make a greener (if not green) version as a headboard covering.
The original is the brainchild of designer Itay Ohaly who hand injected the bubbles to create his pattern. (No permanent link, but if you go to "Works", and then scroll to the last icon on the right, you'll find it).
So what can I inject into the bubbles, that won't dribble out? Food colored mashed potatoes? Just kidding. Maybe food colored glue - the flour and water paste type. Any Ideas?
