I'm currently working on things for post-graduation, but in the back of my mind and in my breaks, the experimentation continues.
John brought over a slightly thicker-than-normal polyethylene bag Monday which I filled with Oobleck. When the bag is filled with stuff, the effect is not that interesting; the Oobleck doesn't really solidify under pressure--it just spreads, for the polyethylene is slippery. However, if empty most of the Oobleck out of the bag, leaving a thin layer of it sandwiched inside the bag, and then stack bag segments, the effect is fantastic. The material resists pressure, but then slowly oozes away. This would also help with the separating problem, for if there is only a little bit of the Oobleck between polyethylene sheets, there's less room for the liquid and solid to spread. I need to buy some polyethylene sheets and work more on this idea.
I've also been outsourcing my experimentation. Aaron has been working with gelatin and just sat on a slab of it for an hour. Initially, the material is like a thick rubber, but after sitting on it for a while, his body heat made it more pliable and gooey. Unlike Oobleck, the gelatin does not separate, and its properties stay relatively the same over time. This would add a different dynamic to the project, but perhaps an interesting one. I need to go out and buy a bunch of gelatin and experiment.
