The "Did You Know?" Thread

Did you know... that the lack of gravity in space would make it impossible to stack Coke bottles all the way to the moon and back. Learned that in 3rd grade science class. :ezbill:

You must of failed the 3rd grade then, there is a very small amount of gravitational pull on the moon's surface.... How do you think we kept a module on it when we landed there? Why didnt Neil Armstrong just "float" away? :idunno:
