Building a hot air balloon (sort of)

I just had an idea for something which might look awesome, but I don't know if it's possible to pull it off... Building lanterns in different colors that can lift up from the ground.

So I've got a question, which some here might be able to answer: How big would such a lantern have to be to lift itself and maybe some lenght of fishing line off the ground, if the air is only heated by a tealight?

The lantern of course would have to be as light as possible. I don't know how much a tealight weighs but I'm guessing somewhere around 25 grams, so maybe the weight of the lantern with light should be somewhere around 50 grams. How much volume would one lantern need to lift off, repsectivly would a tealight produce enough heat at all?
