Two things: firstly, the name of the site is 'What If?' and then immediately underneath this heading it says 'answering your hypothetical questions with physics, every Tuesday' ........ so, if I have a burning question I would like answered at midnight Tuesday I have to wait a whole week? This is just not good enough!
Secondly: the question was asked by an 8yr old ...... I have a feeling he won't get past the first line of the reply !
