In poor areas,few children own toys and they have to do houseworks for example washing clothes.
The children use washing mallets to beat clothes by the river.In view of this, we design Child-like Washing Machine ,
this design unifies the trampoline and piston principle.Put it in the shallow river,when kids jump in it,the piston will
retract with kids'jump.This design will wash out clothes by squeeze and bleaching of river,then put it in the shore
to dry clothes.It not only brings much pleasure to children,but also develops a good habit of diligence.
