I like to use the bags they put on the clothes at a dry cleaner, they are big and really thin.
I use two strips of folded paper that are taped in a cross. This gives a platform for my little birthday candle, and spreads the bag. I gather the edges of the bag and tape them to the paper cross to close up most of the bag.
I pre-fill the bag with hot air from a hair drier. Then I light the candle, and watch it fly. Works really good in a cold gym – cold, calm air and high ceilings.
