     DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0025]    Referring now to the drawings in greater detail, FIG. 1 shows the present invention  1 . The present invention  1  is an entertainment device for use, primarily, in water. The present invention would be used in order to skip it over the surface of water by throwing the device so it hits the surface of the water at an angle so it will bounce off the surface at least once. This type of game has been played in the past by skipping rocks off the surface of the water, however, the use of rocks has serious drawbacks. Since the rock is heavier than water, once the momentum of the rock over the water stops, it sinks and can&#39;t be used again. In addition, if there are people in the water, the rock could strike them and cause injury.  
         [0026]    In order to avoid these problems, the present invention has been developed. The present invention  1  has a circular shape with a top and bottom  2 . The top and bottom surfaces are joined by side edges  3  to form a disk shaped object. Where the top and bottom surfaces  2  join the edges  3  the joint  4  is rounded , as shown in FIG. 2, to present a smooth surface for handling and throwing by the user and, also, to prevent any sharp edges that could cause injury to someone who might accidentally be struck by the device.  
         [0027]    As shown in FIG. 3, the device  1  has an interior  5  made from a soft foam material, to prevent injury if it strikes someone. Also, the foam interior  5  has a density that is less than the density of water so the device will float. In this manner, a user can throw the device at the surface of the water trying to make it skip over the surface as many times as possible and when the momentum of the device, over the water, stops the user can easily retrieve it to throw it again, since it will float on top of the water.  
         [0028]    In addition, the device is provided with a waterproofing coating  6  which covers the entire top and bottom  2  and the sides  3 . This coating will prevent the soft foam material of the core  5  from absorbing water, which would cause it to sink and possibly prevent the user from retrieving it.  
         [0029]    In order to increase the user&#39;s grasp of the device  1  and to thereby increase the velocity with which the user can throw the device, the device can have a coating  7 , as shown in FIG. 4. The coating  7  can be anything that will increase the coefficient of friction of the device. For example, the coating could be any material that will adhere to the device and could include particles such as, but not limited to, sand and pumice. Preferably the coating  7  would be applied to the sides  3  so when the user grips the sides of the device in preparation for throwing, his/her fingers will have a firm secure grip. This will help the user to propel the device with as much velocity as possible, thereby increasing the distance the device can be thrown, and/or the number of times the device can be skipped over the surface of the water. It should be noted that the coating  7  can be any type of coating that will increase the coefficient of friction, but it should not interfere with the waterproof coating that helps prevent the device from sinking.  
         [0030]    In addition, the coating  7  can be applied only to the sides  3  as shown in FIG. 4, or it could also be applied to one of the top or bottom. This would allow the user to hold the device so the coated top or bottom is pointed down when it is thrown. The coated to or bottom surface, along with the side  3  would then be sure to strike the water. This would give the device increased striking power when it hits the surface of the water which would increase the number of times it will skip over the surface of the water. If desired, the top and the bottom and the sides could be coated with the coating  7  so the user will not have to hold the device so the coating is down before throwing it.  
         [0031]    The present invention allows a unique method of skipping the device over the surface of the water. In addition, more than one user can enter the water and the device can be thrown by one user toward the other user without fear of injury. This will eliminate the need for a single user to retrieve the device after he/she has thrown it, which will increase the enjoyment of using the device. In addition, the device can be used by teams to play games similar to hockey or soccer. Also, since the device is made from a soft, foam material , it can be used indoors by skipping it off hard surfaces such as floors or tables.  
         [0032]    Although the Entertainment Device for Skipping Over a Surface of Water and the method of using the same according to the present invention has been described in the foregoing specification with considerable details, it is to be understood that modifications may be made to the invention which do not exceed the scope of the appended claims and modified forms of the present invention done by others skilled in the art to which the invention pertains will be considered infringements of this invention when those modified forms fall within the claimed scope of this invention.
