Playing boardgames and tabletop RPGs can bring you a lot of surprising benefits, but it's not as fun when your dice keep rolling the same result over and over. This simple trick can help you make sure all of your D6s, D10s and D20s are perfectly balanced.
This video from YouTuber Daniel Fisher demonstrates how a simple technique used by golfers to check golf ball balance can be used for your dice as well. Grab a cup, fill it with 1/3 of a cup of room temperature water, and add about six tablespoons of salt. Drop your die in and spin it around in the water. If your die keeps stopping with the same number facing up, something inside the die is making it unbalanced. The cause could be a manufacturing defect or even the cheap filler substance some dice makers use. If you want to avoid unbalanced dice in the future, clear dice make it a lot easier to spot any imperfections.
