WHAT a strange shoe! A Japanese shoe designer (设计师) made these high heels (高跟鞋). When people walk in these shoes, they plant rapeseeds (油菜籽) in the soil. Pressure from the walk can push out a seed from a tube (管子) inside the heel. Rapeseeds can remove dangerous things in the soil that came from the nuclear (核能的) accidents last year.21ST
