Nothing to do with struthious stress management tactics.
(apparently, that alleged behaviour has never been observed)
Excuse the poor picture. And that I've 'borrowed' the puzzle from one I bought from a dollar shop. (the only detail that I have is that it was made in china.)
The puzzle has two 3x3 grids. and 6 1x3 bars. The bars have glow-in-the-dark alien heads (depicted as white rectangles) and holes form them to be accommodated. (depicted as cross hatching). The bars are presented side on. The holes go all the way through. The heads completely fill any hole that they occupy, so you can't put two heads in one hole. madam.
The aim of the puzzle is to create a nice smooth sandwich of:
3x3 grid;3 bars; 3 bars; 3x3 grid

I have a doubt. Why do we need the two grids for? It seems their only purpose is to keep the other pieces in place. So, is the puzzle equivalent to arranging the 6 bars to form a
2 X 3 X 3 sandwich?

Yes tseuG, you're right.
Sorry I took so long to reply- I forgot about this thread. 
The grids are there just because I want to help people find the puzzle in cheap-as-chips shops (if they want)....
No you dont need the grids. You can mock it up with a few striops of paper//cardboard, a hole punch and blue tak if you like.

Maybe the puzzle would be more interesting if the grid did not have holes everywhere?
Maybe you could have holes slightly too small here and there?

I came up with 2 solutions just with pen and paper. Represent the holes as -, the extensions as | and the flats as 0 and put them together in 3 lines and 3 columns to end up with nothing but + and 0. There are a few starting deductions you can make.
1. There are only 5 holes. That limits your options considerably.
2. Using #2, you can tell exactly where # 3 must go.
3. Once 3 is down, there are only two places 4 can go. Both of them lead to a solution fairly quickly.

Have only found one solution- it just looks very different upside down, thats all. If you can show me two distinct answers, that'd make me very happy..

I also see only one solution, except that 1 and 6 can be exchanged, of course.
