if your going to do it.
Buy some eye drops .
My healthfood store sells a small brown glass jar with eye drops in it.
Dump out the eye drops, inject some BA then suck shake it untill it all drops out.
The vial will have a tiny opening in the top for the eye drop to form and fall out into you eye.has a nice screw on cap and all.
It is just the right size to fit a syringe into to draw up the oil inside the eye drop hole
I can fit 3 cc into it.
I did this while driving across the country last year.
so if i ever got pulled over the cops
a cop would find one needle in the glovebox and no gear.
No about doing it on a plane ? Who knows
