Brian Torres (a teacher at Springville K-8 in Beaverton SD) sent me a great video showing a balloon their school launched a couple weeks ago. The students and staff put the whole project together; a great success too!
They attached a camera and it made it to 102,000′ before crashing back to earth in the Gifford Pinchot NF somewhere north of Carson, WA.
Notice the nice ice halos way up in the cold air partway through the video…enjoy!
