Making apple slices that don't brown!

For Clayton's preschool class last week, I was assigned the task of providing a fruit snack for the class. Clayton requested apple slices with caramel dip.  And thus my dilemna - how do I prepare apple slices for 22 kids,  two hours ahead of time without them turning brown (and without having to buy a dozen lemons).

The answer? Seven-Up!  Pour some Seven-Up in a large bowl or tupperware. As you slice the apples, toss them in the bowl of Seven-up.  Keep the apples submerged in Seven-Up until you are ready to serve them. Drain the Seven-Up and rinse the apples with water and you have freshly cut apples that aren't brown!
