A fun game to confuse your brain and make you surprisingly thirsty.

All at the same time!

Click on the Add buttons to increase the volume.

Click on the Empty buttons to empty out the beaker completely.

Click on the Transfer buttons to transfer the volume from one beaker to their respective companion.

And after a little mental gymnastics, a few minutes of staring at the screen, second guessing your moves, and switching back and forth more times than you'd care for:

YOU WIN!

Enjoy!
