We took some construction paper we had lying around, some popcorn kernels and packing tape and went to work!
Here are the steps:
1. Open salad container and add about 1/4 cup of popcorn kernels (unpopped)
2. Close salad container and tape shut
3. Wrap container in construction paper color of your choice
4. Cover completely with packing tape
5. Decorate as you see fit. We used stickers :)
6. Enjoy your shaker!!!
The end result looked pretty neat. See it in action below:
