    I wonder if water balloons/sandwich bags filled with that stuff might be similarly useful.

    As soon as it leaves the pressurized can it expands and then hardens in less than 30 seconds, so it wouldn’t really work in balloons or sandwich bags

      But a Google search says it doesn’t expand without exposure to moisture?

      If it’s pumped into water balloons and the water balloons are kept sealed, I wonder if it would still expand.

        Hm, interesting. I’ve never tried the balloon thing to be honest. I guess it normally uses the humidity in the air, because I never had to add water when I used it in the past
