Tongs for manipulating shish-kebob on a barbeque grill, the tongs having two arms, the two arms being in parallel relationship at an insulated handle end, which includes a pivot point, the arms diverging at the opposing end of the handle end, to form two opposing, spaced apart arms having kebob engaging ends, each end having a horizontal slot formed in the tip of the kebob engaging ends, the slit having a notched closed end, the slot and notch for the receipt of the ends of a skewer, the tongs being compressed so that the kebob engaging ends engage the outer food items on the skewer preventing their rotation so that the kebob can be flipped for even cooking on the opposing side and for removal from the grill.

An overflow prevention container or a boiling container has a bottom member configured with an underside connector plate having a first portion in contact with and a second portion of various contours extending in a thermal separation from the external surface of the bottom member. A thermal gradient is created between first and second portions, thus forming thermally distinct sides of the cooking vessel, causing liquid in the vessel cavity to circulate with a horizontal convectional flow pattern, resulting in prevention of the liquid medium from spillage from the vessel cavity. Grooves on an internal surface of the bottom member terminate in a jump board to provide directional constraint to the liquid as it is being heated.
