member 44 of rotatable member 34 through figure extension 48 . each main body 42 has a vertical length which ranges from about 12 to about 48 inches , desirably from about 18 to about 46 inches , and preferably from about 24 to about 42 inches . main body 42 has a rotatable collar 47 connected to the lower end thereof which is connected to an aperture 45 of inner tube or figure extension 48 . figure extension 48 of figure 40 includes generally from about 1 to about 20 apertures , desirably from about 2 to about 15 apertures , and preferably from about 8 to about 12 apertures in order to provide a predetermined height to figure 40 in an up position as shown in fig1 . the apertures can be spaced from each other at increments of about 0 . 5 , 1 , 2 , 3 , 4 or 6 inches or the like . tube 48 has a length generally from about 24 to about 60 inches , desirably from about 36 to about 56 inches , and preferably about 54 inches . lower end of figure extension 48 rests against the lower portion of an extension figure connection member 44 . figure 40 in some embodiments also includes one or more arms 46 which are optionally movable from a down position to a raised position and are connected to main body 42 , see fig1 . if desired , a football helmet can be attached to the upper portion of main body 42 utilizing any suitable fastener such as screws , nuts , bolts or the like . each figure 40 individually has a greatest overall vertical height ( i . e ., top of helmet if present as in 40 b and 40 c of fig1 ) measured from a ground surface or the bottom of base 20 of generally from about 4 feet to about 7 feet , desirably from about 5 feet to about 6 feet 10 inches , and preferably from about 5 feet 6 inches to about 6 feet 8 inches in an upright position as shown in fig1 . thus , each figure 40 simulates a football player of a predetermined height . figure 40 tube or figure extension 48 is connected to figure connection member 44 and a fastener is inserted through aperture 45 of spin collar 47 connected to main body 42 to operatively secure figure 40 to rotatable member 34 . in a preferred embodiment , the spin collar is utilized so that figure 40 main body 42 can be turned or rotated on an axis perpendicular to rotational axis 35 while the collar 47 remains fixed to figure extension 48 . in some embodiments collar 47 does not spin . the ability of the body 42 to turn or spin aids in absorbing shock or energy transferred to the figure when hit by a football . if desired , main body 42 of figure 40 can be directly connected to connection member 44 of rotatable member 34 . in one embodiment as illustrated in fig1 – 3 , an activation mechanism 60 is utilized to move rotatable member 34 from a first position to a second position . a piston
