Liquid core dice are fascinating. Their moving, swirling interiors catch the eye and add a touch of magic to any tabletop game. But do the presence of air bubbles in common liquid core dice correlate to the quality of  liquid core dice?

Do Air Bubbles Affect Balance?

A common question about liquid core dice is the presence of air bubbles in the liquid. These bubbles can add to the aesthetics of the dice, but can also raise questions about their effect on balance.
What the bubbles do: Air bubbles are typically small and move as the die rolled. Because they are lighter than the liquid, they typically rise to the top, but like other inclusions, they not fixed in one place during rolling. This movement means that it is unlikely that bubbles will consistently bias the dice towards any particular side.
In short, while bubbles may appear to affect the outcome, their effect is small and negligible for the average tabletop gaming session.

Physics in Liquid Core Dice Construction: Rolling and Randomness

When it comes to liquid core dice, a common question is whether the liquid inside the dice, internal inclusions, or even air bubbles affect their balance. There is a concern that these elements may bias the dice toward a particular face, affecting the randomness of the roll. However, this concern may not be as significant as it seems.

Behavior of Liquids and Inclusions

When the die rolled, the liquid and inclusions inside do not remain fixed. They continue to shift, rotate, and move, preventing any particular face from always being favored. This dynamic movement ensures that no particular side becomes heavier or lighter, significantly affecting the outcome of the roll.
As long as the force of the roll is strong enough to cause the dice to tumble correctly. The internal ingredients, whether liquids, inclusions, or bubbles, will not have a noticeable effect on the randomness of the outcome. This makes liquid core dice just as fair as traditional solid dice in most tabletop gaming scenarios.
