Wizards and witches are most famous for their flying broomsticks. It seems science fiction, but can it be done? What about love potions. Could those also exist? Can something be ingested to change neurotransmitters and give a love feeling. Since no one has thought about how they could work, I am going to imagine how they would work.
A flying broomstick would not be able to look like a broomstick, for their must be some modifications to make it aerodynamic. Wings are not needed, as a jet propulsion system can work just fine. The stick must behave according to the weight distribution along the stick, in order to balance the stick. So there must be some computer that senses weight and acts accordingly. Tiny jets under the stick will hover the stick and balance it as well.There will be a much bigger jet behind for providing forward velocity. These jets must be powered by nuclear fusion, as it is the only most powerful energy source for its size. An aerodynamic suit must be worn that also functions to stabilize the stick like the back wings on a plane. Controls must be avaliable, like a joystick, to steer the stick. The leg rests can function as throttles.
Another possibility of magic turning to reality is a love potion. When you fall in love, you release dopamine, which makes you euphoric, and addicted. In addition, norepinepherine, which heightens attention and activity, is released. Low seratonin also contributes to this. Hormones like oxytocin and vasopressin drive attachment to the person. A drug that could manipulate these hormones could make someone fall in love. The issue is how to focus the attachment hormones for a specific person.
What about the infamous invisibility cloak? Well, its a reality already, so no use imagining how it would work
