is this legal to do?

can i show my two hole cards during play?

if there is much money in the pot and there has been a reraise and many calls that one and I GO ALL IN with A,A.
I dont wanna play 2 or more opps, I am satisfied with the money in the pot allready SO I SHOW MY ACES when i pushes all my chips in - is this legal to do? I prob will be beaten by someone if it turns out to be a multipot, so i try to scare them.
