I was walking to the science museum and I saw a sign that said that there was a pretend  time machine in the space hall ,in the museum.I quickly  ran to the museum and ,to the space hall to look at the time machine and when I got there I went to have a look inside the pretend time machine when I saw a big red button and I pressed it,I thought it would go forwards but it seemed to be going backwards , I was confused  why would it go backwards, why not forwards this could change history for ever!
