Abstract: A mechanism for supplying a dilute fertilizer solution to a multiple number of growing plants includes an apparatus for adding fertilizer concentrate to a stream of flowing water, such that a relatively constant ratio of fertilizer to water is achieved. Pressurized water is diverted from a water passage into a container to achieve a fertilizer pumping action. A bag-like membrane in the container forms a pressurized water space that is in pressure contact with a separate fertilizer-containment space. Fertilizer concentrate in contact with the membrane is thus pumpd out of the container and into a stream of water flowing through the water passage. A constriction is provided in the water passage to achieve a pressure drop that produces the desired pumping action.

Abstract: A saddle connector for attaching an amusement balloon to the upper end of a carrying rod (stick). The saddle connector includes a slotted post and four arms radiating outwardly and upwardly from the upper end of the post. A tail area of the balloon can be extended downwardly through spaces between the arms and then around the post to attach the balloon to the connector.
