This is a super easy toddler craft. I remember making these when I was little. It's a good way to reuse old food containers one more time before recycling. All you need is an empty container of oats and a needle. You could dress up the outside of it if you wanted to, but I certainly didn't.
All you do...
1. Eat lots of oatmeal.
2. Wipe out container with damp paper towel.
3. Use a needle to jab a bunch of holes in the bottom (with no pattern and at various sizes)
4. Point your new creation at the light and gaze inside at the night sky!
