Inspired by a design i saw on youtube (https://www.youtube.com/watch?v=TQYBoMxKiSs), i decided to make my own version of this In shell egg scrambler, that allows you to mix the yolk and the egg white without breaking the shell, resulting in a perfect golden hard boiled egg. The object is composed of two parts that need to be locked together with bolts and nuts and the egg must be placed inside them with some fabric or sponge around, to ensure it sits firmly while spinning. In order to make this gadget spin correctly you need to allign the center line of the body with the center line of the two triangles formed by the wrapped ropes as shown in the pictures.

P.S. I suggest to try this gadget outside, at least for the first time and to use a cord that is tough enough to withstand the stress generated by the process
