Dori had fun finding the hidden treasures in this water bottle turned treasure trove. It's a cute activity that could easily be made at home.
Simply dry out an old water bottle, drop in a dozen or so household items, then fill it the rest of the way with rice. Make a list of the items on a card (ours is covered in clear Con-Tact paper) and attach it to the neck of the bottle with ribbon. Make sure the lid is screwed on tight. It wouldn't be a bad idea to wrap it with electrical tape to be safe.
Either let the child discover items as they wish, or challenge them to find the white button or find the green paperclip.
A friend gave us this bottle. She and several other mothers of homeschooled preschoolers got together and each made up enough of the same activity for every family. That made it quick and easy to do, then they distributed them so each family went home with a bunch of new games and activities to do at home. Most of them were fit into standard gallon-size zipper bags. Her daughter is older now, so she shared some of the activities with us. They have worked really well to keep Dori constructively busy while Addy and I do school.
