An apparatus for teaching a person a technique for striking a volleyball. The apparatus has a chute with first and second side walls for directing volleyball toward a pivotable arm attached to the chute. A passage in the arm connects a cone thereon with a source of vacuum while the weight of a valve on the arm positions the arm in a vertical position. An indexing member sequentially retains volleyballs in the chute and sequentially presents a volleyball to the cone. An input acts to release a lock on the indexing member and thereafter allow a volleyball to roll from the chute toward the cone where the vacuum sucks the volleyball onto the cone. The weight of the volleyball causes the arm to pivot from the vertical position and rotate the volleyball to a position for a player to spike the volleyball.
