Unplugged theme of the week is Plastic. Although very late, here is my plastic activity contribution: Straw Snakes. Simple, but thoroughly enjoyed by my four year old.
It started with some scissors and straws. I let him cut them into any size piece he wanted. We had super skinny, super long, and everything in between.
Then he threaded the straw pieces onto a shoelace (you could also use yarn with tape at the end or a pipe cleaner). Ta-da! You've got yourself a pet snake.
