How do you soak your worms?

As the girlfriend doesn't like the idea of live mealworms I've always bought dried worms. Now spring is well and truly springing (witnessed great tits collecting nesting material just now!) it's important to give the dried mealworms a good soak to ensure the chicks get sufficient moisture.

As such... how long and how do you soak your meal worms? I read a blog on here that mentioned overnight but on the packaging it was just for a few minutes in warm water.

Also, the mealies float, how do you ensure they all get a good soaking?

Thanks! Also, any tips on keeping live bought mealies (not breading them!) will be appreciated incase I "accidentally" purchase them :)
