Happy Grammy

Got this soap making kit for four of my grandchildren ages 4 years old to 8 years old. Although the younger ones needed a bit of supervision, they all thoroughly enjoyed the experience of making the soap and ended up with a variety of colors and shapes. The hardest part according to their mother was waiting to use the mold!


It was really good and the girls like it. I think it was good to have the two molds and the girls liked making the crystals. Overall a great kit.


Both my 11 year old son and 7 year old daughter loved making these soaps! They made about 5 different versions - with different colors and shapes. It was fun, interesting and produces something useful.
