Abstract: A circulatory water flow sensory system having a water nozzle attached to a basin. A pump sends water from the water reservoir through the nozzle and into the basin. The water then drains from the basin into the water reservoir. The basin is shaped in such a way to allow easy and safe access to the flowing water for children, especially those with developmental disorders such as autism.

Abstract: An improved filtration device capable of filtering and storing liquid which can then be removed from the device for analysis. A top cap is placed over a filter cap such that a seal is created between these two caps. The filter cap has an opening on its bottom end which is covered by a filter membrane. A storage reservoir is created in the device when the top cap and the filter cap are sealed together. These caps are then slidably received by a vial containing unfiltered sample such that a seal is formed with the interior wall of the vial and the outer wall of the top cap. A needle with a needle housing pierces the top cap and forces the device downward which directs the sample in the vial through the filter on the filter cap and into a storage reservoir to be removed through the needle.
