For this craft we included various textured objects to include in an ice sensory play experience. You can use the red cup to freeze your objects if you would like, or find other sized containers to use. All you will need is water, food coloring (not required, but a fun addition), utensils to dig with, and a freezer!
Place your objects how you wish in the container you are freezing them in. Then add water (and food coloring, if using) and freeze. When they are frozen, take the ice outside and play! You can dig out objects, watch them melt, speed things up with warm water, etc. The whole point is to experiment and explore.
