A This vs. That Brain Teaser


Above, two barrels. The barrel on the left is filled with water that is 84 degrees (F). The barrel on the right is filled with water that's 29 degrees (F). A golf ball will be dropped simultaneously into each barrel from the same height. Assume currents, viscosity & pressure are the same. In which barrel will the ball hit the bottom first?

Please share your guesses in the comments section. And good luck.
