I was shown by an anaethetist a technique to 'blunt the needle', so the pop
can be felt.
Take the a standard needle and back rub it on a piece of sterile guaze,
several times. This blunts the acute angle on the needle, but still allow
easy penetration of the skin. I am convinced that this leads to a 'pop' if
in the right place.
