Here are some photos of my sensory bin I used with my 1 year old. I actually left the blue lights in here from the light box I had made and covered it with a white towel then lined it with cotton balls. The blue lights shine through a little bit, just enough to give it that glow that ice sometimes gets when it's really thick.
CAUTION: DO NOT TRY THIS WITH THE LIGHTS! I had to take my lights out today because they got nearly hot enough to melt the toys inside. Just use some tissue paper or foam under the towel or no towel at all. Just to eliminate the fire hazard completely. Sorry.
The snowflakes are cut out of wrapping paper. There is metallic wrapping paper for a frozen pond with a small snowman figure.
After L played awhile, I decided to give him another empty bin to transfer the cotton balls into since he mostly wanted to take them out of the bin. Also, we added some measuring cups for scooping and pouring.
We also made sparkly snowflakes with glitter. We used the printable pattern from here. I was going to let the kids cut them out, but once folded, it was too thick for their little scissors to cut through, so I did it for them.
