It's often said that true magicians never reveal their secrets. But in the era of technology, it's getting more and more difficult to hide a reasonable explanation from a skeptical viewer.

We at Bright Side are ready to demolish all the illusions surrounding these 10 incredible magic tricks.

10. Turning coffee into coins

This trick from David Blane is popular around the world. The magician takes 2 plastic coffee cups, cuts one in half, and fills it with coins. Then he makes a tiny hole in the bottom of the big cup, puts a sponge inside, and places the cup with the coins on it. Now all he needs to do is place his finger inside the hole. The small cup will go up, revealing the coins, and the coffee will be absorbed by the sponge. The rest is just acting!

This trick, performed by James More on Britain's Got Talent, has a simple explanation. The magician has a special construction underneath his clothes. When he falls on the "sharp" sword, its tip hides and he balances. On his chest is a mechanism that pushes a fake sword out. This all makes it look like the magician has been impaled on the sword.

8. Pulling cards out of thin air

The magician uses a special card holder and puts it on the back of his hand. With a dexterous movement, he pulls cards "out of thin air." Some magicians can do this without a device, but they have to really master their skills so as not to get caught.

This trick requires a lot of preparation and sleight of hand. The magician exchanges a bullet signed by an audience member with a wax one, loading duplicates into his gun. When the gun fires, the wax bullet melts down, and the spray of hot wax puts holes in the glass. The magician gets the original bullet out of its shell, concealing it in his mouth until the reveal.

The key to success here is tiny holes at the top of the balloon. The magician puts a balloon in his mouth and presses it against his tongue so the air releases. This creates the illusion that the magician is eating the balloon. But he needs to hurry after he inflates the balloon if he doesn't want to get caught!

It's entirely based on the laws of physics. A real truck runs over the unprotected magician but doesn't harm him. The key to the successful trick is a set of counterweights on the far side of the truck, not visible to the audience. The weights shift the balance of the truck, allowing the wheels on the lighter side to roll over the top of the magician.

A cut rope is magically back in one piece...but the magician actually never cuts the rope. He has a short piece of rope concealed in his hand and cuts that instead. Using sleight of hand and pulling the short rope up, he creates the illusion of restoring the rope only by magic.
