Good to see you here again. Hope things are well with you and your family.
Yes, that squirt is quite "evil" if it gets away from you. I demo my pump on the DVD with a small tip and show how beaded drops become a rather hefty stream with just a tiny tip and the added backpressure. I wish I could put some video up on APUG, but there is no facility for it, and I don't feel like "donating" the footage to youtube.
I am working on double runs and they are not easy. I have one that runs for over 3 hours, but so far it is too messy for the average person. It would challenge a big lab I think.
