Thanks for the heads up! Fortunately, he's talking more about the "cartoon world" kind of evidence...like being able to hold it's shape, that kind of thing. He's autistic, so emotionally, he's younger than his 14 years. (Even as his mom, I sometimes have to remind myself of that.)
There are substances sort of like that if you want to show him, although water isn't one. They're called shape-memory alloys and shape-memory polymers.
