Science Magic Tricks

Many of you have written to ask me "what exactly is a science magic trick?" In this article, I define "science magic trick" as well as explain my criteria to identify and teach a trick that's based on science. As you will see, some of the tricks are actually stunts that are science lessons, while others are tricks that have secrets based on scientific principles. And still others are simply optical illusions or exploit a quirk in mathematics. 

Science magic tricks look like...MORE "magic," an effect with a secret. But with science magic tricks, the secret is a scientific principle or concept - from either chemistry or physics - that looks like a "magic" trick.

Magic Versus Science Quiz

Can you tell the difference between a magic trick and a scientific principle? And what is the difference between a magic trick and one based on science? Take our fun quiz to find out.

You can perform science magic tricks as straight-out tricks or use them as opportunities to demonstrate or teach a scientific concept of physics or chemistry. Here are science magic tricks that you can learn and perform. In this collection of tricks, "magic" is "science" and "science" is "magic."

    Card Magic.

    Here's a card trick that is actually a science magic trick. In typical magician form, you have a card selected but later find it in an unusual way. This card magic trick relies on a well-known compound that marks the position of a spectator's selected card in the deck, and with a light push, separates the deck at that point. This turns a card magic trick into a science magic trick.
