Here is pro tip for you, if you do any Open Travelers (aka Invisible Palm).
DO NOT show your hand empty on the first card. Keep it palm down. Spread the fingers... leave the people wondering how exactly you palm the card. Even make a fist... then go down and conclude the first effect. On the second time you can show your hand empty. But only very, very briefly. On the third time you can be all "open" about it.
