A Homemade I-Spy toy:
All it took was an empty water bottle, some rice, and a handful of small items we had lying around (a stray crayon, a rubber band, a flag sticker, seashell, starfish, a penny, 2 different colored paperclips, a googly eye, a snowflake (scrapbook), a balloon (also scrap foil). You can really use anything you can fit into the bottle!
(I tired to shake as many items to the top of the rice as I could just for the picture...harder than you'd think! )
It took me under 5 minutes to put it together.
For little kids, it is the perfect I-Spy game, for older kids- combine it with a timer and see how long it takes them to find whatever item you name, or all of them or see how many items they can find in 10 seconds, etc....the possibilities are only limited by your imagination!
