My best guess would be lots of ice....tequila, blue curacao and grenadine...and maybe vodka...it seems like they tip 4 bottles...it's been my favourite drink for 6 trips, then last fall I got hooked on mango colada...yummy !!!
I've watched them make them for me quite a few times... Unfortunately... I drank them after they made them, and therefore can't remember what was in them.
