Having any exposed electrical contacts with any potentially dangerous amount of power would exclude you from even displaying the project in working form in most Science Fairs. You need to ask the people running the Science Fair for specific guidance.is having exposed contacts that are at the voltage going to hurt my chances of winning.
Maybe. Mormans, Muslims, and others have religous beliefs that may subconciously affect their judgements. Teachers, Parents, and others may not appreciate any advertising materials in school settings. This is one of those, "If you have to ask" questions, you already know "it is best not to". Come up with something to cover up the potentially offending advertising. Consider making creative use of the space by displaying a project schematic or something project related.Will the box's reference to alcohol influence the judges' decision?
My system uses 1800 volts as a maximum operation voltage, is having exposed contacts that are at the voltage going to hurt my chances of winning.

Yes but you "manufactured" a new circuit and "assembly" from them so the configuration hasn't been evaluated for safety, so you are outside of what most Science Fair venues would allow to be demonstrated without some safety barrier. Because your project must be connected to the electrical grid and a variac is not a preset unalterable current limiting device it probably would not have been allowed to even be plugged in so coming up with a safety barrier isn't an option.none of the components have been modified in any way, and all were taken from what I assume are UL listed pieces of equipment
I was refering to some dielectric breakdown or sneak leakage path for current that might have lost or diverted current/charge/power away from the expected kinetic energy result. It is up to you to figure out if this is or isn't related to the variac overheating. The two may or may not be related even if they did not occur at the same time. In other words, some flaw or inadequate dielectric might be responsible for causing the energy loss in your experiment and causing an excessive power draw through the variac and the resulting fire. It is also possible that two totally independent causes exist.1). do you mean the electrical breakdown that caused the variac fire or the breakdown that caused the unexplained data point?
