I did some more testing. I tested dropping dice in water. I used a dice tower.
The result were different from my first test but they were not significantly different. The Chi-square results were all well in the range of being random.
Some of the other results:
406 100.00% Total Dice Throws
69 17.00% Ones
88 21.67% Twos
63 15.52% Threes
64 15.76% Fours
62 15.27% Fives
60 14.78% Sixes
Chi Square results for 5 degrees of freedom
Probability for 95% = 11.07
Probability for 5% = 1.15
Chi Square = 8.00
402 100.00% Total Dice Throws
69 17.16% Ones
62 15.42% Twos
66 16.42% Threes
71 17.66% Fours
65 16.17% Fives
69 17.16% Sixes
Chi Square results for 5 degrees of freedom
Probability for 95% = 11.07
Probability for 5% = 1.15
Chi Square = 0.81
