Ok I think I've got it, but I don't want to ruin it. If you can find out how Blaine does similar tricks, it becomes obvious how they must be doing this one.
No camera trick needed. The last trick requires so little sleight of hand any of us could do it with a couple practice runs. grimcity, think about how the hole in the glass got there, and it should be obvious.
Bad choice of words. I don't mean they edited it, I mean that, at the very least, the host can see what's going on. This trick is better done for a videotape or a large crowd than someone in the room.
The glass panel he's working with is set lower in the table than the two on either side. I'd guess that the panel slides back and forth as needed, and that the section his hand is covering for most of that trick has a small hole or section he can move aside.
5:26 you can see he slides his hand across the table rather than lifting and placing it. With a little more pressure he could just be sliding the glass.
Very well done though. I have no idea where he's palming and moving the coins in the other tricks, though I suspect that his large ring is magnetic.
As far as the earlier tricks go: he clearly has a trick coin that folds/opens to look like two stacked coins. For example for the one where three coins on top of the glass suddenly turn into two on top and one in his hand underneath: as he's setting it up you can see (especially at 1080p) two of the coins always moving exactly together even when he only touches one of them. Presumably when he slams his hand under the table with the 3rd coin it causes the fake coin to automatically fold up. Once you assume has the folding double-coin and magnetic ring most of the earlier tricks are pretty easy to follow.
For the table: I'm guessing the moving surface section is spring-loaded to go back to its original position. This would explain why he has to slide his hand to drag the hole into position at the start of the trick, but doesn't have to drag it close again. Instead he kind of wiggles his hand as if controlling the amount of friction so that it doesn't close too quickly.
You can also see the hostess's hand move along with the table at one point. I'm not sure if she was pushing it or she just happened to have it resting on the glass when he was moving the layer with the hole.
You may as well go ahead and click the video and watch it on YouTube in HD, that way when you exclaim "the fuck!?" you know what you just saw was in the highest amount of detail available.
