When we purchased the fairy eggs we also received free 2 packets of grow snow and 1 packet of grow diamonds. They are all very small to start with, then by adding water they grow. We slowly added the water to the grow snow and as you mixed it the snow grew. It was really soft and fluffy to play with. We tried to make a snowman but it didn’t stick together very well. We also made small snowballs and through them into the container. This stuff can be messy so I was trying to get the boys to keep as much in the bowl as they could. With the diamonds, they just needed a glass of water to be added to them. They also ended up growing to soft diamond shapes and were see through. These were harder to find when they landed on the floor, but still fun to play with. You can get them from here when you buy the fairy eggs.
