ELI5: why does water taste so wierd after eating pineapples?

After eating pineapples, the taste of water is very bitter in a sense and this aftertaste stays for some minutes altogether...
Is it something you guys have experienced, or just something personal...?

Pineapple contains bromelain, which is a proteolytic (protein destroying) enzyme that gives pineapple its distinctive tingly taste. The bromelain is interacting with the taste buds of your tongue, and altering their sensitivity to certain stimuli. This is what causes altered taste when you drink water- you're more sensitive to the taste of dissolved minerals and other substances in the water.
