5 42 Rain Drop Puzzle Goal: Materials: Classification: Remove the glass tube to release the $1 bill. Spalted curly maple, walnut, cocobolo Take-apart

6 42 Rain Drop Puzzle Solution: Remove the base (by pulling straight off in a downward movement) and set aside. Remove Cocobolo magnetic top piece. Lay Rain Drop on its side, find out which side you can hear the steel ball rolling around on by tilting it end for end. This is the side you want facing up. Take the magnetic piece and wave it over the face side of the lower base section. Pick up the steel ball and try to "drop" it into the middle area, there you will find a small hole to hide the "size" of the ball. You will know when it has fallen into the hole by two ways, first, you may hear it fall into the hole, it has a quiet yet noticeable sound. Second, when you gently tilt the puzzle from end to end, you shouldn't hear the ball rolling around anymore. Gently roll the whole puzzle box onto its next adjacent side (being careful not to spill the ball out of the hole, keep tilted back just a bit). Now roll the Rain Drop over onto its face side, the ball should be trapped within the hole in the block. The block can now be jostled a bit to allow the glass tube to be slid out through the bottom and be removed from the puzzle.

25 53 TetraCubed Puzzle Goal: Materials: Classification: Fit all eight pieces into the box so that the cubes do not touch each other. Also, make a solid figure from the four dark pieces. Wood, plastic Put Together and box-packing, and dexterity

26 53 TetraCubed Puzzle Solution: Hint: This is really three separate problems: 1. Build a regular tetrahedron using the dark pieces 2. Fit the tetrahedron into the box 3. As you close the box, place the cubes into each of the four empty spaces Solution: 1. To put the tetrahedron together, notice that the 4 pieces are two mirror-image pairs. Each piece has 6 triangular faces and 2 quadrilaterals. The large quadrilateral face has a right angle corner, and the smaller one doesn't. Take two of the identical pieces and put the two smaller quadrilaterals together. This will make one edge of the tetrahedron, and leave 4 triangular faces together opposite the edge. Put the other two pieces together (to make the opposite edge), and put the two sets of 4 triangles together to make the large tetrahedron. 2. To put the tetrahedron in the plastic box, just make sure each edge of the tetrahedron is exactly on the diagonal of a face of the cube. You will find that the empty spaces between the tetrahedron and the cube exactly allow for one of the small cubes to be in each corner of the box that doesn't have a tetrahedron vertex. 3. Use two small cubes in corners to hold the lower half of the tetrahedron, and then to hold the tetrahedron in place (with one hand) while putting the top half of the plastic cube on with the other. If you let one of the small cubes stick out a very little bit, it will hold the top half up so you can insert the last two wood cubes
