I think I can understand it now
Maybe the iron containing water made it turn black because iron deposits in ulcer patients even make the wound area black
Wow, that's really a great practical science
The price is friendly too
Wow beautiful pictures also
When will I be to this area😢
I don't know much science but I guess you're right. It's a good experiment in a science class too, 😅
Place is really nice. Thanks for the compliment!
Don't worry, in time, you can visit this area! Let's just keep doing our best!
I guess all I have again is still the hope 😂
Thanks for your nice reply
We should never cease to be hopeful 😅
