In case you were wondering how strong tempered glass is

The water acts as a weight dispersement. It's not like having another board underneath, but it helps.

Even though the rock is actually on the glass? I know liquids can't be compressed, but I'm really intrigued by whatever transfer of energy is going on with that. It would have changed things a lot if he started with the bigger rock, but I wasn't sure about the delibrate addition of the water. Is it pressing in on the rock as much as is it resisting being displaced (in this case the result being deeper water, but that is pretty relative)? Very interesting. See how much I can learn from fish?
 
does it basically lessen the differential in pressure between where the rock is sitting and where it is not? If that makes sense?
 
I agree that 10 gallon tanks are not usually tempered and I would be willing to be it is not tempered.
 
In essence, yes. It also puts pressure on the sides of the tank, which works to hold the structure together. By having water filled up, it equalizes the pressure on the sides (not the bottom) to help it maintain a rigid form. The weight differential is diffused by having partial pressure on all parts of the bottom sheet.

Wouldn't the water have to be contained in order for this to happen. Any load transfered to the water would just displace the water. I deal with loading often, but never with liquid, so just a guess.

That's a good point, because unless you do 10,000 it could always be blamed on sample error (bubble in the glass or something). Either way, I'm definitely not standing on it, when it goes, it will go big, and the non-tempered glass could be ugly to fall on.
