Clang! 

The second the tip of the chalice entered the small river, it made a clunking sound as if it was hit by another metal. 

Grey hastily tried to remove the chalice after what seemed like a single drop of water entered. However, his expression changed when he realized he was unable to drag the chalice up. With much difficulty and reinforcement from all his elements, he only managed to raise the top a few inches away, before he dropped it on the ground, beside the river. 

The stop he placed the chalice sank down from the heaviness. 

"How's this possible?" Grey's brain went into overdrive, trying to think of what could make just a single drop of water possess such heaviness.
