power point

it is friday today.
at work all seems to be done (already? hm...)
am trying to lear how to make powerpoint presentation in such a way, that when you open it it pops-up directly as a presentation and not with a side-panel on the right hand side and the top bar above...
did not figure it out yet.
can someone help me with that?
"THA" as yorkshire folk say
