How do you keep minnows alive?
Here's what I came up with.
You're going to love this because I figure you're a handy guy with a lot of outdoors savvy.
Take a old or extra cooler, any size.
Purchase the cheapest 12 volt bilge pump you can find and place it in a corner of the cooler
Run a piece of PVC pipe vertically within 6 inches of the top of the cooler and attach a 90 degree elbow,
Take another piece of pipe into which you have drilled a number of holes 3 inches apart.
Cap one end and attach the other to the elbow.
Run a waterproof power wire out of or through the side of the cooler [sealed with caulk] and attach it to a small 12 volt battery or even 8 D size batteries.
YOU"RE DONE!
Now you have a custom made minnow support system and you can still use the cooler if you just pop the pump out.
TA-DAH!
