As you know the design studio where I work occasionally has to photograph food products. Sometimes these food products are packed in dry ice... we're not ones to miss an opportunity to have some fun, so we grabbed a trash can and filled it with water. Then Cory (my boss) broke out his soccer (football) skills and proceeded to bicycle kick the dry ice pieces into the drink. Results: A lot of rolling fog and a lot of fun!
Of course don't try this at home (although trying this at work is encouraged)... but not without gloves and your bosses supervision.
This is Cory after eating some spicy Schezwan Chicken.
