It’s not a conscious step to make intro for kid about skeleton. This is very quick idea and 15min project just for fun. This kind of toy make sense for kids different muscles and coordination. Even older kids (close to 30 years) make fun of that. Construction costs are 8 EUR
4 wheels with bearings, 16 screws and plywood panel – thats it!
Speed, agility and stability
Great deal with lot of lessons for kid. This is sense of true joy?
