Devices, systems, and methods of the present disclosure are directed to providing a Science, Technology, Engineering, and Mathematics (STEM) based distributed games that allows two or more teams of players to develop mathematical and problem-solving skills. Game controllers allow each team to submit a number to a game device that performs one or more arithmetic operations on the set of numbers to compute a guess that is compared to a puzzle solution. If the guess equals the puzzle solution prior to a timer time period expiring, then the players win a reward, such as deploying a shower of confetti, providing candy, display of lights, conspicuous sounds, vibrations, and/or the like.

A handheld novelty device that utilizes a bag structure having a first flexible plastic sheet and a second flexible plastic sheet. At least part of the bag structure is transparent so that the contents of the bag structure can be viewed. The first flexible plastic sheet is molded or bonded to the second flexible plastic sheet in selected areas. This defines a plurality of interconnected chambers in the bag structure. The interconnected chambers include a first chamber, a second chamber and a meandering pathway that interconnects the first chamber to the second chamber. Flow material is provided that at least partially fills the plurality of interconnected chambers. The flow material can be a liquid with floating solids, or a slurry of solids and liquids. The flow material is displaced within the plurality of interconnected chambers when at least one of the plurality of interconnected chambers is compressed.

The invention is a noise-making device for sports venues, cheering venues and the like that provides a body and a head attached to the body. The device can be mechanically or electronically activated for both light and sound. The head of the device can take many different forms but is universally applied to the body.
