For the most part, the old alchemists and magicians were fooling their audiences with plain ol' science. If you knew nothing of chemistry, the sight of water turning instantly into oil would seem like witchcraft.
But even for us jaded modern types with our fancy "education" and "skepticism," science can do things that not only seem like magic, but make magic tricks look like a bunch of ridiculous bullshit.
5You Can Make Objects Look Possessed Using Vibrations
As awesome as the concept of telekinesis is, it's remarkably hard to do, and if you pull it off, the government will almost certainly hunt you down and/or force you to join a team of crime fighters. Pretty much every "He's moving things with his miiiiind" trick is easily explainable as either sleight of hand or some neat physics cheat code.
But where magicians fail, science delivers -- here's a handful of sand, moving by itself and forming patterns like it's practicing the halftime show for the Super Bowl:
Later in the video someone spills beer on the sand and it starts drawing dicks.
And here are some drops of water calmly ignoring all laws of physics and walking on the surface of a pool:

All the more reason to never pee in the pool.
Science's much more awesome version of this trick is done with vibrations. That masterful sand dance is just a day at the office for cymatics researchers, who study visible vibrations and how frequencies relate to geometric patterns. The higher the frequency, the more complex these sound-shapes get.

It's the same thing with the water trick: Putting speakers under a water container makes the fluid vibrate and causes small droplets to bounce on the surface indefinitely. Boom up the bass, and they'll happily cluster and bob along until the vibrations end. Then the party's over, and the drops become boring, normal water again. Scientists call these wandering droplets "walkers" and use them to study the dual relationship of particles and waves.
However, you're not going to be dazzled by mere water and sand. You want science to really impress you. So let's see what the vibration trick looks like with some non-Newtonian oobleck fluid:

It's like a T-1000 had a wet dream.
Apparently, all it takes to create an angry, sentient blob monster is cornstarch, water, and dubstep.
