Safety:
The hot air stripper achieves high temperatures and if misused will cause severe burns. This piece of equipment should be only used by a competent adult.
Flying the balloon
(with a responsible adult)
Support the clay drainage pipe on a tripod. Using considerable care place your balloon over the end of the pipe.
Place the electical paint stripper (hot air device) underneath. Start with a low setting to inflate the balloon.
