Locating an air leak in a bouncy castle can be done systematically through a few methods:

1 Visual Inspection: Carefully examine the entire surface of the bouncy castle. Look for any visible tears, punctures, or damage to the material. Pay close attention to seams, corners, and areas that are more susceptible to wear and tear.

2 Soapy Water Method: Inflate the bouncy castle and mix a solution of soapy water. Apply the soapy water using a sponge or spray bottle to the inflated castle, especially focusing on seams and suspected leak areas. Watch for bubbles forming at the site of a leak. The escaping air will create bubbles in the soapy water, indicating the location of the leak.
