One square of paper, about two minutes. Americans mostly call it a cootie catcher; in the UK it is a chatterbox, and origami books file it under salt cellar. Same object, same seven folds.
You get a four-pointed shape that sits on your fingertips and opens two ways. Someone picks a number, you work it open and shut while you count, they pick a colour, and the fortune under that flap gets read out.
What you need
- One sheet of paper - printer, notebook, or a 6-inch origami square
- Scissors, or a hard crease and steady hands for tearing
- A pen, plus coloured markers so the colours read at a glance
Fold on a flat table, not your lap. Crisp creases separate a cootie catcher that snaps open from one that flops.
Which paper works, and how to square it
Printer paper is the right answer for a first one. It creases hard and takes pen without bleeding. Notebook paper works too. Stay off cardstock: eight corners fold into the middle, and heavy stock bulks up so much there that the flaps stop closing. Save it for a paper crane.
The square has to be square. Fold a corner across so the short edge lies along the long edge, crease hard, then cut or tear off the leftover strip. Six to eight inches suits adult hands; below five there is no room to write a legible fortune.
The fold sequence in plain language
Two diagonal creases to find the centre. Four corners into that centre. Flip it. Four corners into the centre again. Fold the small square in half both ways, then push your fingers into the four pockets.
The flip is where people lose the thread. Turning it over hides the first round of points and gives a clean face for the second. Skip it and the pockets land on the outside where fingers cannot reach, which is why half-built ones refuse to open. The origami basics guide names these moves properly.
What to write on it
Write before you pop it open, while it is still flat. Numbers go on the four outer flaps, colours on the eight inner triangles. Lift each triangle and write a fortune underneath, eight in all, six words or so each.
- You will laugh before lunch
- Something you lost turns up this week
- Ask again after dinner
- Today is a good day to be brave
- You owe someone a thank you
- Wear your lucky socks tomorrow
- A small mistake works out fine
- Say yes to the next thing offered
Teachers can swap fortunes for questions: times tables, spelling words, state capitals.
How to work it
One digit into each pocket, thumbs and forefingers, then pinch until it points. Open it by spreading your thumbs away from your fingers. Close it. Spread the other way, so it opens front to back instead of side to side. Alternating those two directions is the bit people get wrong: open it the same way every time and half your fortunes stay hidden.
Variations
A 10-inch square makes one small hands can work. A class set goes faster if you print the number and colour grid onto the squares first. Kids who take to this want the rest of the notebook-paper canon - a paper airplane, a ninja star, a paper football.
When it goes wrong
The flaps will not open. Nine times out of ten the two half folds got skipped. Flatten the small square, fold left to right and crease, unfold, then top to bottom. Those are the hinge.
The corners do not meet in the middle. The square was not square. Fold it corner to corner and check the edges line up. Out by more than a millimetre or two, trim and refold.
It splits at the centre. Too much rubbing back and forth over one crease, usually on thin or damp paper. Set each crease with one firm pass of a fingernail or ruler edge. Tape on the inside holds it, but the flaps never sit flat again.
