Gear box

This is a gear box that I created. It’s a great example and toy for teaching kids about how gear boxes and gear ratios work. Not only is it a great educational toy, but also a great fidget to express your stress or rage. This model is great because each gear requires either a larger or smaller amount of energy to be able to turn. This way, you could judge accordingly based on your level of emotion and fidget with this amazing gear box. Hope you like it!
