Re: More destructive air tank testing from 95

Nice work! Now I think we just need to see the non-clippard plastic tanks tested.

From this video, it's clear that Clippard's updated tanks (the black ones) can explode just like the old white ones. They removed the screw fitting, which removes one significant source of stress on the tanks that had been proven to cause issues, but they didn't remove the real worry - the failure mode of the tanks.

Personally, I don't really care about the rate of failure for any tank... it's the specific failure mode that concerns me. The metal tank in the video pretty clearly has a better failure mode than the plastic one - it didn't send shrapnel flying all over the place.

Given the abuse we put our robots through (I've seen things bent and broken on the field that you never would have expected to be damaged!), it's really surprising we haven't seen more of these plastic tanks explode. I know that my team will never again use plastic tanks on the robot - It simply isn't safe enough to allow them to.
