Edinburgh Casting Studio Family Casting Kit Refill - Hand Casting Kit Refill with Alginate Molding Powder and Stone Cast for Family Kit

I purchased this for an activity to do with my 3 grown children during our Christmas together. It was great fun and a really cool idea but we had to do it a second time. I set the water at just the right temperature but it activated too quickly. We couldnt push our hands through. So next set we set the water temp a little cooler. We had to sit still a little longer but it was worth the wait! My 3 grown children and I holding hands. It makes a mom's heart happy!! Thank goodness i purchased and had that extra bag of casting powder!!
