- How does the explosive gel not blow up inside of the can when Batman presses the button?
- It could undergo a chemical change when it exits the (perhaps reacting to oxygen) that makes it explosive while the rest in the can would be inert
- Why doesn't Batman ever add something in his costume so that he would get a warning in case of the air he is breathing is toxic? For the first chronological game it is plausible but after that it is a wonder why its never mentioned he is not using a detector or adding something to his mask for it
