Items needed
- a pole or yard stick
- string cut into 4-5 foot lengths
Have someone tie their string to the pole and see if they can pull the stick off the ground and try to make it stand straight up.
Then have some one else tie their string on and see if it works with two people. You can keep adding one by one, or just show how when everyone isn't working together it won't get the job done.
Tie everyone's string onto the pole and at the same time everyone pull on their string to lift their weight of the pole so it will stand straight and strong.
