Given the rise in obesity the range of bodyweights amongst youngsters is widening.
In the playground, this may mean that any two children are unable to enjoy a see-saw together.
Today’s invention is therefore a see-saw mechanism which measures the weights of two children who sit on it and subtly shortens the side on which the heavier child is seated -so as to bring the device into balance (probably by sliding the seats along the seesaw rail).
This means that both fat and very skinny children get a chance to play (and exercise) together.
