Amazing and magical productions that keep happening - SIX times!
Show a large bag to be empty. Reach inside and remove a large bottle of soda! Place it on a nearby table. Do this three more times, with all four bottles on display.
You now show the bag empty once again, only to be followed by two more large bottles - six in total! And just to nail your audience, pick up the final bottle you produced, open the cap, and pour some soda into a glass. If you'd like, drink some!
