Alcohol and chem dispenser nozzle gun

[Frank_Stein]

How about a little hand tool that's connected to a hose

Take it off, use in hand to dial in different combos, and click on beakers to dispense

Move a distance away and it snaps back

Dispense directly from the machine, or use the hand nozzle mix a lot of batches quickly

---

And of course, use the nozzle on yourself to drink from it or use it to spray others

Add a suicide option where you put the nozzle in your mouth, set it on full blast, and you pop.

This seems extremely useful and I'd like it a lot. We after all already have distance-based snap-back on objects like phones
