As soon as you drop the egg on the floor, cover it completely in salt. You may need to use a cup or more. It's important that it is totally engulfed in salt.
Step2
Wait ten minutes.
Step3
After ten minutes the salt will have absorbed all the liquid of the egg yolk and the egg and salt will become a solid mass. At this point you can simply sweep it up with a broom and throw it away!
Tips & Warnings
It's much easier to pour the salt on the egg if you twist the top off the shaker or pour directly from the large salt canister.
After you throw out the egg/salt mixture you might want to spray some kitchen cleaner and wipe up with a paper towel.
