I did my first GooKit about a week ago - blue water, red goo in a 32 oz. Lava Lite globe. Turned out excellent. I used 6ml of surfectant. It flows great, but all the blobs are perfect medium-sized globs of goo. No stretchy globes, no different sized globs, really.
Would adding more surf change the flow? It doesn't flow like my 90s lamps, which I'm ok with. I'd just like to see more stretchy flow instead of perfect globs going up and down.
