This is an easy project that entertains kids longer than you would think possible.
You will need a clear bottle. I used a 2 liter soda bottle that I bought for the single reason of using it for this project. My kids rarely get to have soda, so that was also a treat.
Fill the bottle 2/3 of the way full with birdseed or rice. (I chose birdseed because I can reuse it to feed to the birds, unlike the rice. You will be tempted to fill it more than 2/3, I know I was. But don’t do it. It makes it impossible for the birdseed to really move inside the bottle and for the “treasures” to get lost and found inside.
Go around the house and find little things to put inside the bottle. Basically anything that will fit through the small hole on the top of the bottle is good.
I put inside:
as well as a few tiny random toy pieces I found lying around the house.
Screw the lid on tight.
The give the bottle to them and let them shake, roll, and smack it to find the little “treasures”
More fun than you would think possible.
