I was in Creative Mode when I got the weird idea of throwing Enchanted Apples into the ocean.

When I threw the Enchanted Apples into the water, you could only see the texture of a normal golden apple. The purple enchantment foil was nowhere to be seen.

I then picked up the apple again because I thought that Minecraft might have programmed it to wash enchantments off the apples - but no.
I got an enchanted apple again (luckily)
