This invention provides a weighted tarpaulin (tarp) that allows for water, as a weight, to be readily introduced to a tarp when installed and distributed effectively around the tarp to ensure it remains securely engaged against the roof or other surface across its entire surface area. The tarp comprises two layers of durable polymer that are welded or otherwise adhered to define a series of interconnected cells in a grid pattern. The cells can be filled with water from a hose, via fittings. The tarp includes an extended material strip that extends beyond perimeter cells so as to provide a surface to receive supplemental / optional fasteners. This strip can include holes / grommets for such fasteners. The cells meet at a series of junctions that provide fluid connection therebetween. One or more cells can include a small valve to allow bleed-off of air and water.

A toy hand comprising a plurality of fingers, each having a nail attachment surface and a recessed opening at one end. The toy further includes a plurality of removable nails, each having a nail portion and a coupling structure configured to engage with the recessed opening of a corresponding finger. The recessed opening and the coupling structure are designed to form a mechanical connection that allows the removable nails to be securely attached to and detached from the fingers. This system enables repeated customization and replacement of the nails without the need for adhesives or tools, ensuring ease of use and durability. The invention may be implemented using various coupling structures, such as plugs, hooks, or magnets, and may be constructed from durable polymeric materials. The toy hand is particularly suitable for applications involving creative play, allowing users to decorate and modify the nails repeatedly without damaging the toy.
