Dear Peter,
How is it going?Recently a competition over technological innovation has been held in our school.In the competition,I won second place and my magic shoes are thought highly of.I've longed to invent a pair of shoes to help my feet keep dry.Therefore,this new kind of shoes has come into being.
To meet the demand,this new kind of shoes is equipped with a micro﹣fan.When we walk on the road,a small machine inside the shoe changes the energy produced by walking into electric energy and stores it.If we stop walking,the micro fan can work immediately to dry our feet.In this way,we can keep our shoes dry all the time,especially in summer.
By means of creating my magic shoes,I have learned what can't be learned in class,which leads me to explore a new world and have a clear mind of what I want to be in the future.With more creative ideas,I'm sure we'll enjoy an easy and comfortable life.
That's my magic product.Do you like it or would you like to have a try?
Yours
