How-To: Glowing balloons change color to show air quality
glowing balloons.jpg

Honestly, they had me at “glowing balloons.” I’ve got a box on a shelf in my closet that houses my past, failed, experiments to make floating, glowing party balloons. The group at Carnegie Mellon that produced this Instructable makes it work by using weather balloons which are bigger and can provide more buoyancy. That the LEDs they use are tri-color versions that change to reflect the ambient air quality is just icing on the cake. [via Boing Boing]
