I bought one of those Quick Minnow Containers where you can get the minnow out and not get your hands all wet, plus it's easy to carry when you wade. I tried it out at home with some dead minnows I had in the freezer, and it doesn't seem to work. I only put a few in there, but I figured at some point when using it, I'd be down to a few and it should still work. Does it matter if they are dead? I'm just tipping it down, and trying to get the minnow to the top like the instructions said. What am I doing wrong?
