White Star Balloon Valve Vacuum Test Video

A detailed technical video demonstration of the vacuum leak test we're doing on the vent. We're using this one-way vent valve on the bottom of the balloon to keep the helium in, and the air out.

We have been fairly quiet publicly, but many subsystems are coming to completion rapidly, including the  helium gas overflow vent valve.  Completion of anything flying on a ballon means it's time to do some science!  Tests must be done, data must be noted, hypotheses checked.  Gary Flispart and I put together a detailed technical video explanation of the vacuum leak test system we've made.


Stay tuned for more updates at , we are on track to launch in the next month or two!

    Hi Dan!

    Great science post. I've learned some great tips and tricks from this video. I would like if you post more videos on helium balloons.
