ABSTRACT:
A portable amusement device wherein flotation of participants occurs on a continuous basis within flotation devices comprises a plurality of trough defining segments each being formed with double side walls and end walls with the double side walls defining a hollow section to permit nesting of the individual segments for shipment and storage. The trough segments are joined to one another to form a continous trough with a pump in at least one hollow section to continuously move a flotation medium throughout the trough and thus propel participants therethrough.
