Rip open the cereal
box and cut a large circle out of one of the sides using a compass or
sauce pan lid. Lightly draw 2 - 3 further circles inside. They should
be about 3 cm apart and are only an aid. Draw in the best spiral you can
do using the circles as guides, leave a nice big (6 cm) circle in the
centre. Using the scissors cut along your spiral line remembering to leave
the centre intact.
Using the plasticine, secure a sharp
pencil in a upright position just above a heat source such as the back
of a TV, or the back of a fridge, or the top of a radiator, or a mantel
piece. You can even place it on top of black card in the window sill.
Balance the centre of the spiral on the tip of the pencil. Do NOT poke
a hole in the spiral you can dent it slightly but do not puncture it.
If you do, a piece of sticky tape will repair it. Let the spiral hang
down. If it hangs lower than the pencil cut it off at the correct height.
The spiral will whiz around for hours
on end, all by itself! How does it work?
