Yes, I also did a similar holding the end of the candle in my fist so as to create a vacuum such as it would in your ear. I let it burn down just as far as it would in your ear - to about 4" - and when finished, the end of the candle was full of "earwax", in fact it was blocking the open end of the candle and some had dripped out.
This concerns me not just for effectiveness but safety.
