Jambin and I cooked some green slime today. I used the Easy Slime Recipe #1 from this site but the cornflour stayed very lumpy in the mixture, so I think if I used the same recipe again, I would mix the cornflour to a runny paste with a small amount of water before adding it to the saucepan containing the boiling water.
Pushing the mixture through a tea strainer (the only strainer in my house) wasn't very effective as the unmixed cornflour soon coated the strainer so that no slime could be pushed through:
So we decided that we would just play with lumpy bumpy slime:
Honestly, Jambin wasn't overly thrilled by this activity. He thought it was kind of interesting for about 5 minutes, we then extended the playtime by letting him coat the backs of my hands in slime, and then he was asking if he could wash his hands. Oh well. It was worth a try.
