Just as a quick note: We had a fixed number of tanks to work with and so we tested the mitigation techniques we saw proposed most often and used materials we had on hand.

We would have tested additional containment methods but we sort of 'expended' all our plastic tanks. If anyone wants to send us more we'd be more than happy to do additional testing.

The aforementioned video will go into some depth about the hows and whats of the testing. For now we thought it was worth letting the community know that, at least in our tests, containment of these tanks failed more often then it succeeded, and that it requires substantially more robust solutions than many expect.
