My boys thought this was the coolest thing. All for the Boys friend Nicola shared this on our Facebook wall but the boys have watched it a couple times I thought you might want to see it too!
2 Canadian teens built a weather balloon structure for around $400 complete with GPS. The little guy reached a height of 80,000 feet and while the GPS did stop working when it was 4 miles up it actually started working again and they were able to find it 75 miles from their original launch point. How cool is that?
