We make many I Spy bottles, but since summer is here, I thought I would share the sea shell one we made today. I like to have the kids help me choose and put together the bottles so they have some ownership over them. They love to do it. I got these shells at the craft store. We found some "summer" items, a lemon, lime and watermelon eraser, foam flower, fish and sea star, a button and a glass marble. I made up a picture card for them of all the things they put in the bottle. We filled it about 3/4 full, put the lid on and gave it a couple turns. Then they got busy searching for the things inside. So fun!
