You mentioned that you are using a syringe.
Where did you get the syringe from?
We live in PA, possibly one of the most restrictive in the US for buying a syringe.
In PA you are required to have a prescription to legally buy a syringe.
Here's the weird parts: That rule ONLY applies to a syringe to use for a human.
A farmer can buy a limited supply at a place that sells animal medications. (The syringe, and the medication are exempt from the prescription rule!)
I have ordered syringes for "refilling ink cartridges" from e-bay at a pretty good price. (new ones of course, do NOT want to try and smoke ink! YUCK)
I guess since the needles are dull they are exempt?
Anyway, thanks PA for your bizarre laws.
