Both siblings get paper and a pencil. Parent names something to draw: a cat, a house, a face. Both draw it from start to finish with eyes fully closed. The blindness levels the field completely — the child who usually feels less capable produces exactly the same kind of result as a sibling who normally draws better. Opening eyes to compare always produces shared laughter.

What you need

paper (one sheet each)
pencil each

How to do it

1Each child gets paper and a pencil. Eyes closed before anyone starts.
2Call a subject — a cat, a face, a house. Draw it start to finish without opening your eyes.
3Open eyes. Compare the results.
4Vote on which drawing has the best accidental detail. Laughter handles the rest.

Variations

If one refuses to close their eyes: let them go second and watch the first drawing happen — seeing how silly the result looks usually gets them in.
How it ends: compare and vote on the best accidental detail, then pin both drawings up side by side.
This one builds cooperation before it's needed. For an active fight, use The Separate Reset (B006-20) instead.

💡 Parent tip

Call categories with clear features: a bicycle (wheels, frame, handlebars) produces more interesting comparisons than something vague like 'a shape.' The more features the subject has, the more interesting the differences between drawings.

What your child develops

Spatial memory — drawing from memory without visual feedback relies on stored mental models of shapes
Shared failure — both children produce an imperfect result at the same time, which removes the hierarchy that fuels sibling rivalry
Fine motor proprioception — controlling a pencil without visual feedback uses a different motor skill than guided drawing
