Going to do and film it remotely for safety, however how much danger would one be in by plugging the below contraption in to a socket?

That 16v cap won't last very long with 230v across it so you'll get a little pop and that's about it. It might make a bit of a mess inside the plug but it's a tiny cap so I think you'll be disappointed

Result: Very anticlimactic, all it did was trip the 20A B type MCB. Not even a pop or a skid mark inside. I guess the Cap's ESR must have been very low.
I have also found MCBs are no good for this sort of experiment, I am forever tripping the 32A MCB. 3036 all the way!
Capacitors, hmm. 4" steel pipe stuck vertically into the ground. Build fire around pipe. Drop full aerosol can into pipe and stand back. Fun for all pyrotechnic personalities, and cheaper than fireworks from the posh garden centre. Wear safety specs.
I heated up a small old capacitor with a hot air gun to watch the top split open. Not noticing that the old design didn't have the score marks that allow it to vent in a controlled manner, the can blew off from the rubber end bung with the most tremendous bang, and with such force it cracked the PCB it was on. My ears were ringing, it was like a gunshot! A number of neighbours came out of their houses to see what was going on! Oops!
