BAGGI BOX CUBE Modification of Giuseppi Baggi's Box to make a cube. The original Baggi Box is rectangular with a double-thickness slanted edge on the inside and outside of two opposite walls. The other two walls are smooth. If a second box is used as a cover for the first box, the inside slanted edges of the cover can catch against the outside slanted edges of the first box, making it difficult to remove the cover. Making the box a cube allows the cover to be rotated 90 degrees and still fit the box, with the slanted edges of each rubbing against a smooth wall of the other. Modification by Bennett Arnstein.

BOOMERANG �� Modification of Max Hulme's Boomerang in the book "Super Simple Paper Airplanes" by Nick Robinson. Modified by John Andrisan and Jim Cowling to make it spin faster and longer. The modification also adds a Kline-Fogelman effect to the underside of the boomerang. As drawn, the boomerang is intended to be launched by a right-handed person. For launching by a left-handed person fold a mirror image.

1

The boomerang is folded from a rectangle. A convenient size to use is half of a letter-size rectangle. The exact dimensions are not critical. One-third of a letter-size rectangle will also work, as will the strip remaining when one large square is cut from the rectangle.

MAJESTIC FLAPPING BIRD by Laura Kruskal �� Material needed: Rectangular copy paper. 8.5" x 11" will not give a very large or impressive wing span, but the wings will flap. Better sizes would be 8.5" x 15", 11" x 17", A4, A3, a recycled paper placemat, or approximately 6.5" x 11" which is 8.5" x 11" with approximately a 2" strip cut off a long edge. Diagrams based on a 6.5" x 11" rectangle. Color side up.

An existing traditional magazine cover box may be reworked to the locked configuration by unfolding it to step 4 and then folding per this page to lock the walls. A locked box may be crammed full of stuff until the walls bulge out, but the walls will not come apart. If you're using a cover for the box, the cover may also be reworked to the locked configuration. C Bennett Arnstein 10 / 17 / 05

Re-close the creases of step 8 while the creases of steps 5 and 6 are partially unfolded. Grasp the noisemaker at the heavy circles, between the thumb and forefinger of each hand. Alternate your wrist motion between E & F. Both wrists always rotate in the same direction, as they go back and forth. Sometimes, depending on the paper you use, you can make a louder noise by rotating your wrists in the opposite direction, as they both go back and forth.

ENVELOPE Origin unknown. John Cunliffe calls it a Scoop Envelope because during one of his folding steps for a split second it looks like a scoop. I learned it from Dr. Milt Sager who said he learned it from somebody during a meeting of the West Coast Origami Guild, a long time ago in a place far away. It could also be called a "Self-Mailer" because it converts a letter into its own envelope, suitable for mailing. I think of it as a storage container for flat modules or squares of origami paper.

Make three modules of different colors for each tile.

Assemble the modules in the flat position of step 5. Insert the tab of the second module into the pocket of the first module. Close flat the crease of step 7 on the second module. Slide this crease along the edge of the pocket until the second module reaches the pointy end of the pocket. Diagrams and text C Bennett Arnstein 5 / 22 / 2006

TRIANGLE TILE Page 2 THIRD MODULE

� � �

11

��

In a similar fashion, place the tab of the third module into the pocket of the second. The pocket of the third module is now the top layer, and the tab of the first module is the bottom layer. Carefully lift the tab of the first module and place it on top of the third module. Then insert the tab of the first module into the pocket of the third module.

Now refold the crease of step 5 on each module, in the sequence shown. Note that the second module is folded first, then the first module is folded, and the third module is folded last. The flap of the third module covers the flap of the first module and goes under the flap of the second module.

13

The tile is finished. Each edge has the same color, front and back.

The puzzle is to arrange the tiles side by side so that they form a hexagon, with the same color edge on both tiles wherever two tiles touch. Since each color appears three times, the third instance of each color must lie on the outside of the hexagon. You can solve the puzzle as you assemble the tiles, and then make a sketch of the hexagon showing the final color arrangement. Then use the sketch to solve the puzzle again after the tiles have been shuffled. Diagrams and text C Bennett Arnstein 5 / 23 / 2006

The pocket of the second module has been wrapped around the tab of the third.

Move the sail of the third module from behind to in front of the sail of the second module.

9

Continue connecting modules until eight modules have been connected. Then connect the eighth module to the first one. In order to get the pocket of the eighth module around the tab of the first one it will be necessary to disconnect the sail of the second module from the first one, and then re-connect it after the eighth and the first have been connected. Make sure that each sail lies in front of the sail of the previous module. This is the front side of the medallion.

This is the back side of the medallion.


The next page shows how to make the medallion spin.

HOW TO MAKE THE 8-WINDMILL OCTAGON MEDALLION SPIN by Yami Yamauchi Make a blow-top spinner from a ninth windmill, using the same size square as was used for the eight windmills to make the medallion. Attach the blow-top to the back side of the medallion by inserting the vanes of the blow-top between the modules of the medallion. This will be illustrated using a "Me Spin Long Time For You" blow-top (see page 22).

2

1

First inspect the back side of the medallion. Notice which direction the vanes of the blow-top must enter the spaces between the modules. For the medallion shown, the vanes of the blow-top must enter in a counter-clockwise direction.

Fold a "Me Spin Long Time For You" blow-top with its vanes pointing in the opposite direction, so that when the blow-top is turned upside-down they will be pointing in the correct direction. Then turn it upside-down and insert the vanes into the back side of the medallion as shown in step 1.

BLOW-TOP

MEDALLION


3

The blow-top has been attached to the back side of the medallion. The medallion will spin if you blow down on the front side, but it will spin faster and longer if you spin it by hand. Spin it on a smooth hard dry clean horizontal surface.

SPIKE BALL MODULE by Rona Gurkewitz & Bennett Arnstein Page 1 �� Start with the Froebl unit, invented by Frederick Froebl, also known as the Pinwheel, or Windmill.

3

Fold one corner to the center, and then unfold. Repeat at the other three corners.

This completes the basic Froebl unit. Rather than flatten the vanes to form a windmill, spread open and squash each vane flat, making the four corners meet at the center.

Mountain-fold both diagonals by sharpening existing creases.

9

Two things must now happen at each corner: (1) Let the corner point on the bottom layer swing out away from the center without making a crease on the bottom layer. (2) Fold the corner point on the top layer in to the center, making a crease on the top layer. Repeat at the other three corners.
