They'll love this one, because it happens right in their own hands!

Show two real, full soda bottles and two tubes with modern graphics. A spectator uses one of the bottle-tube sets and you use the other. Both tubes are placed over the bottles. Now, the spectator must do exactly what you do. Tip the bottles back and forth, then forth and back. Now lift the tubes. Your bottle is exactly right side up. But, his is upside down! How can that be? Try it again. Again, he does exactly what you do. And, again, his is upside down and yours is right side up! On the last try, his bottle finally matches yours!

At the end, you can even produce a third bottle, which you can give your helper as a souvenir!
