This one is simple to build and a lot of fun while play. It’s called the ‘Pogo Stick’. All you need is a piece of wood, some wire, and a few pieces of plastic. The first step is to make the frame.

Finally, glue the wooden rectangles together along one side using hot glue or superglue. Make sure to leave a small gap at one end so that you can fit the plastic pieces in later on. Once the frame is assembled, it’s time to add the fun part: the pogo stick!
