Soapmaking. Well, actually the melt & pour variety. It's much safer for little ones than using lye. And quicker, too.
Each child picked his/her own scent, coloring, and bug/lizard/butterfly for his/her own bar of soap. (We have green apple, strawberry, coconut, and strawberry-green apple. My hands smell yummy. No one wanted eucalyptus or the other scents I have.)
They are anxiously awaiting for their bars to cool and harden.
Did I mention it's a snow day? I may be sending S.O.S. signals today!
