I used to go to a disco at my dads working mens club for xmas when i was really young, the dj used to blow bubbles in to the crowd on the dance floor and if you caught one you got a chocolate bar.The trick was to lick your hand before so the bubbles stick to it, if your hands were dry they would pop 9 times out of ten.I had a good thing going i used to catch atleast 5, then id give up so it didnt look so obvious.
