Today I stayed at B2 floor all day long!
I saw a lot of expansive equipments, each of them costs over one million dollars.
And most of them have to be preserved under low temperature.
Because when using them, they genereated a large amount of heat.
Therefore, the B2 floor is really cold. I wear two long shirt and a coat, but
I still felt very cold.
The equitments generate a lot of harmful substances, so we need some protections.
If we did not have enough protections, we might get hurt!!
Now I going home!!
GO!
