Product Hack: If you find you have a bottle  or prefer to use a brand that the Houdini No Spill slips out of, a simple solution so you can still use a Houdini No Spill is: Take the lid of the bottle you would like to use, cut a square or a hole in the center with a sharp knife and then screw it back on your bottle over the top of the inserted Houdini No Spill. it will hold it in and stop it popping out
