A bat includes a handle configured to be held by a user having a first end and a second end opposite the first end, the first end includes a knob having a larger diameter than the handle. The bat further includes a barrel extending from the second end of a handle, the barrel configured to strike a ball during play. The barrel includes a first layer primarily composed of a single wall aluminum, a double wall aluminum, a single wall titanium, a double wall titanium, a single wall composite, or a multi wall composite. A second layer is connected to the first layer and configured to support the first layer to prevent the first layer from fatiguing, permanent damage, or exceeding applicable rules limiting the hotness of the bat.

Disclosed herein are various forms of hybrid baseball bats comprising a wood shell having a radial wall and an outer radial surface profile defining a baseball bat. The wood shell having a central core with a central surface thereon extending from a distal end of the bat. The central surface being profiled with a taper that in some embodiments extends entirely through to the proximal end. A fibrous construct is housed in the central core and infiltrated with an epoxy resin. In some forms, the fibrous construct is in the form of a sleeve. Disclosed are various manufacturing techniques for manufacturing hybrid baseball bats including a low pressure bladder method, a high pressure bladder method, and a centrifugal force method.

A tunable insert is provided that may be placed within a baseball/softball bat at or near its sweet spot. The insert may allow for fine tuning of the bat's compressive strength, and thus the bat's performance. Two opposing inner sleeves may be received within a tapered inner core and may be drawn together with a threaded fastening member. When the inner sleeves are pulled together, the insert segments are pushed outward. The segmented outer piece of the insert may be directly in contact with a ring member or inner barrel that is positioned between the barrel and the tunable insert. When torque is applied to the threaded fastener, the segmented outer piece expands, thus also expanding the ring member. As the ring member expands, it gets nearer to the bat's inner surface. The relative distance of the ring member to the bat's inner surface tunes the stiffness of the bat.

A snowball launching and batting apparatus comprising a barrel member, a handle member, and a knob feature, the handle member further comprising a primary cradle structure configured to accept, form, and store snow or snowballs. The apparatus further comprises a secondary cradle structure capable of coupling the primary cradle structure and configured to accept, form, and store snow or snowballs. The knob feature may further comprise a depression configured to form snowballs. The apparatus is further configured to have an extended and retracted state. A user inserts snow into the barrel and cradle structure to form a snowball and inserts it into the apparatus while in an extended state. Launching the snowballs from the apparatus may comprise swinging the apparatus or applying a force to the handle member to quickly move it from an extended state to a retracted state.

There is provided a system for hydrodynamic and/or air levitation of an object, such as a ball by a stream of water, and a striking object for hitting the object, and a method of play comprising the system.

A ball bat, extending along a longitudinal axis. The bat includes a barrel portion, an end cap and a handle portion. The barrel portion is formed of a fiber composite material and includes a proximal region having a continuous single wall construction, a central region and a distal region. The central region includes at least first and second central region walls longitudinally extending from the proximal region, and a distal region includes first and second distal region walls longitudinally extending from the central region. The central region walls and the distal region walls form a first inner barrel wall and an outer barrel wall, respectively. The barrel walls are spaced apart by a first separation. The first separation is unfilled and longitudinally extends over the central region and the first distal region wall. The end cap and the handle portion are coupled to the distal and proximal region, respectively.
