me, my father and our team have all brainstormed a whole ton of grabber ideas: first of all, it is our first year and that i'm unfamiliar with alot of terms that you guys might use...a 4-bar? ??? thats an example.

1) pincer - just a pincer with rubberized grips that hold onto one pole.

2) no name - a 2 pronged design that skewers the tetras, then expands (kinda like a pair of doors in an an entrance), eventually expanding to the bottom 2 corners of a tetra and holding them in place by pinning them against a barrier at the back of the grabber. hard to explain.
experiments with straws show that it is possible to skewer the tetras from a wide variety of angles, the tetras are held tight (do not move), and they are held from the bottom, so the arm doesnt have to be as long. my team doesnt like it, but i like it most.

3) 3 pronged grabber (fork) - 2 outer prongs move up and down, central prong remains stationary. central prong skewers tetra apex, the 2 outer prongs lower, making contact with the 2 sides of tetra.
