Step 4Sop up the excess

Sop up the excess
After you've strained all of the casein out of the liquid, you'll want to soak up some of the remaining juice in the mass on the wax paper.

Use a few paper towels, and press gently on the casein. The liquid will spill out like squeezing a sponge. Be careful not to make it too dry, because it will become difficult to mold if it's too dry.

Dang, I read about this in grade 1 and always wanted to try it, but my parents were too cheap to waste the milk! [slaps head] Wait, I'm not a kid anymore!!!! I can try this experiment with my OWN milk! Hot darn! The cheesecloth suggestion for draining is right on the money - way more effective than a colinder. Also, if you are worried about the strength, my thought would be to add fibers of some sort (left overs from a fiberglass repair kit, or even cut up dental floss) - something to add tensile strength to the mix. Any thoughts on colouring with food colour?
