How does a bounce house work?
Inflatable Bouncers (both dry and wet) function by continuous airflow. A powered air blower continously pumps air into the inflatable while it's in use, and air escapes through the seams. Therefore, it's normal to hear air "hissing" out of the inflatable or see bubbles in the water slides. You'll need an electrical plug nearby or a generator to power the air blower.
