If you are an aspiring magician, dazzle your friends with simple magic tricks. Making a coin float on water will be a great addition to any other tricks you have up your sleeve and will have your friends wondering how you defied the laws of gravity. Properly executing this trick can take many attempts; however, once mastered, it will bring you one step closer to professional stardom.
Find lightweight coins. Visit coin stores in your local area and find coins that are made out of aluminium and are lightweight. Japanese 1 Yens, Italian Liras and French Francs are just some of the coins that are able to float on water. These coins are thinner than American currency and are made out of lightweight aluminium.
Prepare water container. Obtain a water tray that is greater than 6"x6". The tray works best if it is made out of aluminium. Fill the tray approximately 2/3 full with regular tap water.
Dry the coins. Before placing the coins in the water, ensure they are dry. Wet coins will not float on water as it changes the density of the surface.
Gently place the coin on top of the water. Holding the coin on top of the tines of a plastic fork, gently lower it onto the surface of the water. When placing the coin into the water, ensure that it is kept level. A coin that is not level will sink, as water will wet the top, making it sink.
Remove the plastic fork. Once the coin is resting on the surface of the water, gently and slowly tip the tines of the fork into a vertical position and pull them out of the water alongside of the coin. Be careful not to cause a splash when executing this step as the coin may sink.
Watch the coin. Your coin should be floating by itself as it is supported by the surface tension of the water.
Place other coins into the tray of water. By following the previous steps, place other coins into the tray of water. Notice how the coins are magnetically attracted to each other.
Shake the tray. Gently shake the water tray and watch your coins separate. After the coins have separated they will be pulled toward each other by way of the aluminum's magnetic qualities.
Practice this trick repeatedly to learn how to make coins float more quickly. This will allow you confuse people with your lightening speed moves.
