How do I check an airbed for puncture holes?

Question

ok, so the bed is a double layered queen size air bed with an automatic pump...so its way too big to do the whole immerse in water to check for air bubbles thing... how else would i be able to find where the puncture/s are??
By the time anyone wakes up after attempting to fall asleep on it, they look like a hot dog in between the bun, lol...any help would be much appreciated thx

Answer 1

Use a spray bottle with soap and water, spritz an look for bubbles.

Answer 2

try listening for the leak or take a sponge and wipe soapy water all over it. its the soap That make it bubble more by releasing the surface tension of the water
