Struggling to get this part completed. I know I need the water from the fountain to use on the box. How do I get the water??!!!

I've tried right & left clicks and I don't seem to be able to scoop up the water in my hand to use on the paper.

Any ideas please?! Thank you

Yea, it a bit tricky, I was stuck there too.

Check the black box. Click on the gold Daedalus logo. Click the lid to see a litmus paper. Click on the litmus paper.
Move cursor to the side of box and get water from the pool. Take the drop of water from inventory and use it on the litmus paper. It worked.
