Hello All!
Back in 2010 Stacy Kuznetsov crated an amazing visual tool for air quality awareness: https://www.instructables.com/id/Air-quality-balloons/
I wanted to know if any of you have made this (I have but in 2012) and/or if you have any leads on recent versions of this tool.
A friend of mine, Max Wakefield is looking to create a set of these for the upcoming UK-wide campaign.
Any leads/ideas would be much appreciated!
Best,
Cindy
I once created a fidget spinner that measured air-quality. The design worked but the wheel bearing for the spinner had some problems.
