Eat the chewing gum
Wait, what?!? That's just...ewww. Do you know how many different types of bacteria there are in the human mouth? For that matter, you don't even know if it was chewed by a human! Fortunately for you, it's not actually chewing gum, but a chewing gum-like plastic called sugru, which you realize before you can put your bacteria-laden lips, tongue, teeth and epiglottis to it. The sugru is doing an admirable job of holding the Arduino to the control panel, so you see no reason to change that state of affairs.
