This is very interesting, Howard! Thanks for sharing! The difference between oil and water based liquids is very obvious, so I think just comparing these two along with air temperature would give a really interesting result for non-science students,…
We have launched liquids (water, water/alcohol mixtures, cola, fruit juices, liquid hand soap, hand sanitizer, oils) on several flights. We use small plastic washing bottles (30 ml Nalgene washing bottles) with the spray tube removed. We never fill…
Hi everybody,
A group of students in my class would like to design an experiment to investigate the behavior of liquids in near space during our May 23 launch. They would like to put several different liquids in plastic containers into a pod and fil…
Dear Bernhard,
Sorry to take so long to give you feedback. Paul Verhage has written an e-book on Near Space Exploration and has discussed several balloon related projects in his NUTS and VOLTS columns. Parallax has links to some of this material on…
Hi everybody,
I'm teaching a course for non-science majors at the moment which includes a balloon launch toward the end of the quarter (May 23). I'm having the students work in teams of 3-4 to design their own experiments for the flight. Ideally, I…
Hi Howard,
We would also like to do a trial run this evening. Did you simply pull out the "Pull before Launch" pin to activate sensors and transmitters and run the test, and then replace the pin after the test to put it back to sleep?

HALO II will be DePaul's second launch. (The first one was the Stratostar training launch we received as part of the system we purchased from Stratostar.) The students who participate in HALO II are all members of DePaul's Society of Physics student…
