Is this one of us???? because it seem pready similar to what project of making.
Two Students Noted For Explosives Research
SOCORRO, N.M. November 10, 2009 – New Mexico Tech students Shaun Geerts and Micah Wild won third place for their research poster at the national
American Indian Society of Science and Engineering conference in Portland in late October.
The mechanical engineering students were honored for their poster titled “A Study of the Effects of Shaped-Charge Liner Design.”
Geerts, the president of the Explosives Club on campus, said he and Wild completed the project with the intention of presenting at the International
Society of Explosives Engineers in Orlando in February.
While they haven’t heard if their paper has been accepted for the ISEE conference, the Tech chapter did receive an award to help students attend.
A “shaped charge” is an explosive charge with a lined cavity that generates a jet of metal when detonated. The standard design includes a liner that
collapses in a fashion that creates a high-velocity jet of ejecta. Geerts said he and Wild tested a theory that a second liner would create a more
powerful jet.
“We came up with an idea to implement an inner liner,” Geerts said. “Instead of a single liner, you have an additional liner inside and the goal was
to add more material to a certain part of the jet to increase its effectiveness. If you have more mass, it can penetrate further.”
The students theorized that one thicker line wouldn’t allow the same initial velocity, but a second liner may allow the jet to form, then add material
as the shaped charge exits the cone.
They tested their theory nine times at the Energetic Materials Research and Testing Center at New Mexico Tech. Two of their designs penetrated a
target object just as far as the conventional shaped charge, but none of their designs outperformed the standard cone, Geerts said.
The national organization gave the club $1,000 to help students pay travel costs to attend the conference. The Explosives Club has about 50 members
and Geerts hopes that 10 to 12 students will attend the conference in Florida.

I get a good feeling reading this, let me explain myself.
I think it is a general acceptance that explosives are only for military/government.
There seems to be a major problem with amateurs/student that experiment with explosive materials.
It is good to hear that there actually is room for this 
@on topic
The idea behind a double liner isn't that dumb, even tough it did not outperform the commercial charge.
I can imagine that there are limits to a single liner and thus there is a frontier in the current method.
A nice way of thinking around the problem.
Too bad my insights in this kind of physics are limited at this point.
What a fine day for chemistry this is.

A non-event, then?

Nothing ventured nothin gained my pessimistic friend!
I agree it is heartening to see non governmental folks sponsored and even allowed to test thier theorys.Even in failure something learned something
gained."Negative waves
man".
'Kelly's Hero's?
Theres a link there somewhere?Like the prize goes to those willing to take chances/try new things.Maybe Edisons a better example.Far more failures
than successes.Stubborn SOB and still a Famous name.Likely more stubborn than genius. Early Happy holidays.
