27. Make Sock Puppet Show
Does anyone not have extra socks lying around? If you find some old pairs, you can try turning them into puppets. All you need is some glue, googly eyes, pom-poms, and some imaginations. Make a couple of your kids' favorite characters; then, you can start a fun storytime with them.
If you have extra time, consider making a theater out of your cardboard. Pain and decorate them for maximum effect!
