Quick Corrode Hooks

Quick Corrode Hooks ?

What kind of alloy would make a good hook AND corrode in fresh water in about a week.
Think something like Sintered Cast Iron would work?
What metals corrode in a few days?

I love to have hooks like this for my plastic worms and my foam poppers. So what if the lure needs a bit more care...

Think about it.
Gut hook a fish or break off a trophy and rest assured it hasn't just received a death sentence.

Or How about hooks lost in those mixed use areas? Be nice to know that hooks lost near the boat dock wont be around to snag a kids foot the next week.

Any metallurgist geniuses out there?
Hey - What did Chrysler used to make those K cars out of ?

'Cause I don't believe most fish survive waiting for a standard hook to corrode, lets keep this thread on the topic of corrosion please.
