The reason for the 'boy' tag is they're very, very quick. I don't know about you but that's certainly music to my ears when I'm doing anything crafty with mine. My boys are often keen, always impatient, and have the attention span of a gnat. So the faster they can see results the better! Yes-No boxes are perfect because they're pretty much instant. This is all you'll need - empty matchboxes and a pen or pencil.
Slide out a tray and draw a two-way face on both sides (there are two trays here to show this). Slide it back.
The kids decorated their boxes too, drawing on sticky address labels, but skip the colouring-in bit if you want. Then the idea is to whisper a secret question needing a 'yes' or 'no' answer into your box..
..shut it, toss the box in the air and pick it up as it's fallen. Open slowly halfway, and the face gives you the answer.
There were squeals of delight and howls of despair - so much fun watching them.
I heard whispers of goals, Arsenal, Disneyland and daddy, the Red Arrows? and something about an iPad (I don't think so..)
and someone obviously thinks they're getting sparkly shoes for christmas..
