Make a tetrahedral pyramid with these puzzle pieces.

Recently on a local fair (mela) I bought this puzzle from a magic-stall. It contains the following parts (each part is rigid, inflexible)

Fig- 1 : Dismantled pieces in 1 set.

It contains :

• rod like piece, containing 4 balls in a straight line: such set 2 pieces.

• Rectangular piece with 6 (= 3 X 2 ) balls, The arrangement of balls is square type : Such set 2 pieces.

• a triangular tray.

All balls are equal in diameter. The balls of a single piece could not be detached or bent.

The whole thing is to be assembled into a pyramid (more specifically regular tetrahedron) , as follows:

Fig- 2: What to attain. The regular tetrahedron shown from different viewpoints.

Assembled piece shows 4 balls at each edge.

Hints:

.................................................

1. completely geometric puzzle.

.....

1. No lateral thinking required.

.....

3. The completed piece would look like a stack of marbles or oranges.

.......

4. the model on hand will make the game much easier.

The way to assemble this is in the following order :

- take one of the long 1x4 pieces.

...

- take one of the 2x3 pieces, and sit it on top of the first piece so that 3 balls appear on each side of the single rod.

...

- take the 2nd 2x3 piece, rotate 90 degrees from the other one, and place on the top of the prior 2x3.

...

- Place the last 1x4 on top of the contraption. This structure, when tilted to any side 45 degrees, will give you the final product.
