Hints for uses in your library Courtesy of Dr Kirsty Ross, University of Strathclyde: Instead of adding scented extracts directly into the balloon, scent cotton balls and push them into the balloon before inflating it. Use latex-free balloons to keep this activity allergy-free. Extend this activity by placing the scented balloons throughout the stacks and sending participants to find them.
