Lana has been tasked with investigating a concern about the "cracking pressure" of a spring-loaded check valve. She compares it to one of the larger swing-gate-style values we have been using, which has essentially no cracking pressure, but can sometimes not close when pressure is too low. She chooses some clear Qualatex 350's for the task, and really enjoys seeing how long she can make them inflate. So much so, she may have forgotten the purpose of the experiment. But that's ok with us.
