You are eating some delicious potato chips. (You can even show your audience the inside of the can.)
Take a tube and place it over the chips. Incredibly it visually changes into another colorful flavor.
Perform again to make it change into a 3 flavor.
For the finale, you place the tube over the chips one last time -- and miraculously each of the 6 chip versions you showed before, all appear as mini containers.
Easy to do.
Fun effect that is extremely visual.
