Father and child place about eight dishes on the floor, about two feet apart. Blindfold a tribe member and challenge them to walk between all the dishes, back and forth, without touching any of the dishes with their shoes. They must not walk naturally and not slide their feet.
After they‘re blindfolded, quietly remove the dishes. After they pass the point where they think the sixth dish is located, quietly place the dishes back. Finally place the last dish in front of their feet, making it touch one of their feet. Have the person take off the blindfold and wonder how they did it.
