Kerrie sent in this fascinating hack:
I have 9 month old twins who seem to have spent more of their lives congested than not. They hate the snot-sucker (even the cool battery operated one!) and I'm always struggling to get their noses clear. The other day as we were headed out the door, they both sneezed as soon as we got into the bright sunlight and voila! Lots of boogers, etc to wipe up, and clear noses. They have a photic sneeze response and will sneeze when they see bright lights. So now whenever they need their nose cleared, we either head outside or have them look (very briefly!) at a bright light. Works like a charm!
I'm totally intrigued. Has anyone else experienced this?
