My hot air ballon a actually made a real hot air ballon but only about 3'by 3' and it was to explain how heat rises and how an actual hotair baloon works . i made it out of paper maseha a coffe can and craft wood . i used a cotton ball soaked in rubbing alchol for the heat source witch i used the coffe can to hold it witch was attached to the actual hot air balloon.

Barry's Response - Dan:

Such simple household items: paper mache, coffee can, rubbing alcohol can be used to make the most classic of experiments. Thanks.
