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. You can perform science magic tricks as straight-out tricks or use them as opportunities to teach scientific concepts. Either way, they’re fun to learn and are sure to amaze your audience. But how can a simple plastic straw—it may be examined before and after—become so rigid? The answer lies in a simple technique that takes advantage of air pressure and good aim. You’ll know the trick but your friends won’t be able to reproduce it easily. Why It WorksWhen the straw encounters the hard surface of the fruit or tuber, air gets trapped inside the straw. This stiffens the straw so it can pierce through the flesh. Once through, the air is released and the straw will be flexible again. When the straw encounters the hard surface of the fruit or tuber, air gets trapped inside the straw.

This one is not only a great magic trick for kids but it’s also an excellent craft activity. Kids can make the tube out of household materials and decorate it as they wish. You can even make it a bet that if they catch the bill, they can keep it. This can be quite dramatic if you are using larger denomination bills. Due to gravity, an object will fall at 9.8 meters per second. The human reaction time between perceiving something with the eye and responding with action is 0.2 seconds. It is therefore impossible for the challenger to respond in time because the bill will fall 20 centimeters in 0.2 seconds and U.S. bills are 15 centimeters in length. The bill will simply be out of the challenger’s reach before they can react. The secret to this trick is the basic principle of water absorption thanks to a common compound found in a few everyday items. As long as you don’t tell, you’ll be the only one who knows about it. While your friends won’t be able to get a paper clip to float, you will. That’s because when they drop it into the water, it will disrupt the surface tension. You, on the other hand, will show them how using a bent paper clip allows you to place it on the surface where it will float perfectly. Floating Metal trick from Tricks Wallet In this science magic trick, you make loops out of paper strips and cut them down the center. The simple cut splits the with varying results: two separate rings, one long ring, or two interlinked rings. While it sounds rather ordinary, the results are sure to mystify an audience.
