Biased Dice video ...

Watch this video and you will see what commonly occurs with unbalanced biased dice:


Video Link ---->  Aces twice, 6/2 five times


What you are Seeing:
1.  a very nice dice laboratory with an excellent security camera system.


2. Biased dice being used in this video. Notice the faces occurring during these 2 streaks are all on one plane -- the 1, 2 and 6s.  This is what happens with biased dice more often than not (see more discussion at Link --> Biased Dice ... )  The 3s and 4s end up as the axles and disappear all too often when the 5 and 6 are heavier due to the heavier resin used in the white pips (dots).


3.  Furthermore, the stated odds by the author on YouTube are for balanced dice, and therefore not correct for this set of dice:
This is a short spurt where I got aces twice in a row followed by 6-2 five times in a row. ... Rolling the same non-pair 4 times in a row after the initial roll is a 1 in 104,976 occurrence .. any initial non pair is a 5/6 chance making the total 1 in 125,971.
4.  Less than 2 minutes from hundreds of hours of video - sure if you toss the dice hundreds of hours at home on your practice table, almost anything can and will occur .... we are only seeing a snippet here as the author notes on DiceInstitute.com: 
"The security camera system runs for every single toss on the table."
What you are NOT Seeing:
1. No proof that he is using fair balanced dice


2.  No proof how old the dice are - most dice are only used for approximately 500 tosses or 8 hours (except Caesars LV) for a reason - they tend to become biased after then on their own .... so is it any doubt that a string of numbers is easier to obtain after many hours of use.
