Where to Hide During a Nuclear Attack

A lot less likely than it once was, but you never know.
Hide in the water tank if you have one.
They are made of steel typically which will shield you from the radiation blast.
Make syre the tank is as full of water as possible. The water will absorb a massice amount of heat.
Water tanks are strong and will protect you from falling bricks and things.
And of top the that there is a lot of water to drink if you get thirsty.
Better do your tiolet business outside of it though.
