After the failure our first attempt to use a clear trash bag as a containment bag for a bursting hot water bottle (poor Misty!), we try again with a thicker, industrial-grade bag. Ava has volunteered to do the huffing and puffing, which she does quite a bit of before discovering that we have a leak due to a faulty rubber seal. Once that was changed, things start to expand properly. She certainly gets a good workout, but is rewarded with the right thing exploding, and the containment bag holding!
