Why does metal spoon taste weird after touching aluminium foil?



I always cringe and unable to eat with that spoon due to the taste and sensation after it touches aluminium foil.
Why is this?

Thank you!

In: Chemistry

Aluminium is a different metal to the steel of the spoon.

It’s quite possible that you just don’t like the taste of aluminium.

How are you with drinking from aluminium cans?

It doesn’t. It’s all in your head. I guarantee if I gave you two spoons. You would have no idea which one touched aluminium foil.

Galvanic reaction. I am very sensitive to this as well.

Essentially, electrons are transferring from the aluminum to the steel.
