## Root Cause

A mattress over a bathtub provides no structural protection from falling debris; it can be blown away or pinned down, causing crushing injuries or suffocation, and the bathtub itself offers minimal shielding.

## Dead Ends

- **Using a heavy wooden table or desk instead of a mattress for extra protection** — Heavy furniture can be lifted and thrown by tornado winds, turning it into a deadly projectile; it also provides no anchoring. (85% fail)
- **Filling the bathtub with water and lying in it for weight and protection** — Water in the tub adds no structural integrity and can cause drowning if the tub is overturned or debris blocks the drain. (80% fail)
- **Holding the mattress down with your body weight to keep it in place** — A human body cannot anchor a mattress against tornado-force winds; the mattress will be ripped away, exposing you to debris. (90% fail)
