How to pronounce “stave”(noun) in English

I came in on a Saturday, and it looked like the barrels were about to explode basically.They were almost like shaking with pressure. There was beer squirting out between the staves of the barrels. And the heads of the barrels were literallybulging. And I panicked, because if one of those explodes, it will be an unimaginable mess probably. And so, I ran and got a hammer and a screwdriver.
