Here I fill with water and then rapidly drain my Intex whale that has a zipper installed on its back. The zipper used is a 24-inch-long Tizip SuperSeal airtight and watertight zipper. The zipper allows the inflatable to be used as a storage bag as well as allowing for extremely rapid deflation, or in this case draining. The zipper is plenty strong enough and holds air letting the Intex whale still be used as a regular ride-on pool toy.
Check out how the zipper was installed in this toy in the video here:
