You’ll need:
•Small Soda or Water Bottle 
•Rice
•Beads, Charms, Glitter, Sequins, Other Small Items
•Small Kitchen Funnel
•Craft Glue
Instructions:
Start out by cleaning the bottle well and removing the label. Make sure the bottle is totally dry before you start this project.
Place the end of the funnel into the bottle and start filling it! Start out with about a cup of rice. You can add more or less if you like. Then, start adding any small items you would like to ‘search’ for in the bottle. It can be beads, charms, small toys, etc. Make sure if young children are helping you that they do not put any of the small items in their mouth. You can also add some sparkle to your bottle by adding glitter or sequins.
Once you have everything you want in your bottle, spread some glue around the threads on the neck and replace the cap tightly. This will prevent the cap from falling off or being removed by small fingers.
In the bottle above, I added several shaped beads. They are shaped like a variety of items such as dogs, boats, hearts, starts, etc. If you add special shapes like this, your noise maker can also be a game. Challenge your child to find specific shapes or colors by rolling the bottle around to reveal hidden treasures.
Do It And How 
We used bird seed in ours. I’ve also made some for a baby shower and put little ‘baby shower’ themed items inside.
