I agree with all, freeing up the innards of old filter caps and even worse, potted transformers can be a dangerous, frustrating, and absoluetely wretching experience. First of all, safety glasses. Please. Outside, yes, always. No flip flops and t shirts need apply. You can't always predict where they will burst, and it may not be where the "safety" vents are. And of course you will permanently pollute any cooking appliance like a toaster oven.

But it is fun.
