(The batch of cement that we mixed with a lot of sand worked much better on the lego men than previous batches with little or no sand. See below. We also discovered that patience is rewarded. If you try to remove cement from molds within a day it's risky. It's best to wait between 2/3 days before lifting out.)
The poor, headless, weak batch of Lego men.
Cement sand castles and ice cubes for building blocks.
I love how this plastic cup mold came out, even the bubbles and holes.
