Magic jumping beans to download, print out and make. Members can download the parts at the usual place, non members can download the parts for £2.50
Print out the page onto thin card. (230 micron or 67lb) Score along the dotted line and carefully cut out the parts.
The main body of the bean is made from two pairs of tubes folded and glued as shown with the black line above right.
Fold each pair of tubes and glue them flat then fold them up and glue them together to make a double tube.
Glue both double tubes back to back being careful to line them up with each other accurately.
Glue one of the end caps into place.
Drop a single coin into each tube. I used UK one penny pieces. They are approx 20mm in diameter and weigh around 4 grams each.
With the four coins in the tube glue the other end cap into place.
Fold over the two sides and glue them down to make double thickness card.
Once the glue is dry cut the shape out.
Glue the sides to the body lining up the cut outs with the grey triangles arrowed above.
Done! Roll the bean down a shallow slope and it will move in a preternaturally jerky way. Weird!
