how does a lightning rod works to prevent your house from being struck by lightning?
If your looking for a step up I would look at the billy allen or a shank snaffle. It's the perfect in-between. I wouldn't get a correction unless your horse needs it, that causes more problems than its worth. All our 2yr old futurity and non futurity bound reiners go into a shank snaffle or billy allen because they are a mild 'step up' bit. Many horses go in them forever. I wouldn't get a pelham, that's more of a hj/eq bit, and your horse doesn't need that. Overall I would suggest the billy allen or shank snaffle, but don't change bits just for the heck of it. If your horse is soft and responsive in a hackamore, keep him in that. Don't fix it if it ain't broke.
That would worrk but make sure u are Very generous with ur glue. otherwise youll end up with water between ur box and ur waterproofing material.
Pond liner. But if you're talking about your 2x2x1 feet box, that's going to be a major PIA. How about epoxy + fiberglass? Apparently, several people have built (far larger) fishtanks in that technique.
go to big lots and buy 2 cans of flex seal spray able rubber
