When Bree gets doused in milk, Adam's reflection in the capsule door shows him with an 'oh' expression, but when the camera cuts to him, he's giving an 'ooo' expression.
When Adam and Chase are each hanging by one hand, it is obvious from their body language (not entirely stretched out, and their hips and torsos fixed solidly in space) that they're standing on a platform which is off-camera. Additionally, the distance between their glued and magnetically locked hands changes from shot to shot. At one point, Adam's hand comes down so far into camera that one can see the controller is no longer in his hand, or at least not as far down as in other shots.
It isn't clear what kind of glue is used to bind Adam and Chase to their game controllers. The bond is instantaneous yet it can't be Super Glue since the controllers completely disappear from their hands after their dunk in a wading pool, therefore revealing the glue to be instantly water-soluble.
