Explore the magic of capacitive touch with this magical potion bottle.  Place the key in the lock to switch it on, then touch the magical locks on the bottle to make it change colors.  Touch the locks in the right combination and the potion will swirl in beautiful rainbow colors.

Professor Snape might actually give you a passing grade for this project, but you'd better hand it in on time.
