My son received a birthday present via UPS and it had green packing peanuts in it. He was having a blast playing (and making a mess!) with the peanuts so I decided to make him a Halloween Sensory Exploration Bin with it. I added all the little Halloween things that we’ve collected though the years. He had so much fun digging through the peanuts to see what he could find! He kept saying “What Else?” and “I found it.” So cute! We have done sensory bins in the past where I have added measuring cups, toy shovels, and his toy binoculars to it as well. Another idea would be to add Halloween candy to it.
