How much salt would I need to be able to float in my bathtub as if it were the Dead sea, would it work?

1. Can I use kitchen salt?

2. Why would it work?

3. Why wouldn't it work?

4. If the answer to #2 is no, why does it work in the Dead sea?

The general rule of thumb for salt water aquariums is 1/2 a cup of salt per gallon. The Dead Sea is 8 times saltier then that so 4 cups per gallon. The average bath tub holds 50 gallons so 200 cups of salt are need. 1 cup of salt weighs approx .6 pounds so you need about 120 pounds of salt. Mix well until all salt is dissolved. Lay back and enjoy your mini Dead Sea.
