This started when my sister-in-law tried a viral TikTok hack—putting a dish soap bottle in the toilet tank to keep it clean. It worked… until the bottle got lighter and started floating, bumping around like a tiny boat, making noise, and occasionally getting stuck under the flapper (not great). She asked if I could fix it, so I designed a simple clip-on holder to keep the bottle steady, quiet, and easy to refill—turning a messy hack into a clean, reliable solution.
