If I was invisible for a day...

If I was invisible for a day, I'd be very happy.  No one could bother me and I'd run around without anyone knowing I was there.  I could just be alone.  I'd also like to play jokes on people, like making things "float" and moving stuff around.  I'd also wrap myself up like the invisible man and pretend to be a mummy.  I don't think anyone would know it was me... unless the nametag over my head was enabled!
