When eating lunch at my desk in the office I'll be squeezing some ketchup packets out onto my sandwich wrapper so that I can dip my fries in the ketchup, and eventually, without fail, one of them will shoot out at an angle or velocity I'm not expecting and end up on my clothing. I've tried ripping bigger gashes into the packet, and while that does tend to fix the problem, it means I'm usually getting ketchup all over my fingers.
What's the best way to avoid this?
