I'm a junior in high school and take a class called EDD (engineer design and development) and I have to create an invention. The invention is a tennis racket handle with a removable ice pack built into it. Our idea would solve the problem of sweaty hands. We were also thinking of including a heat pack attatchment for those colder days. Any feed back or ideas are appreciated. Even if you think this idea is good or bad is appreciated. Thanks,
First, check to make sure someone else has not already invented something similar. A racket handle with anything added to it will throw off the proper balance of the racket, which will detrimentally affect performance. I think that maybe you should alter your idea to something more along the lines of a grip. Perhaps, create a grip that stays cool more easily or hot. A grip with ridges to increase the surface area could help keep the grip cooler. As far as keeping a grip warm in the winter, my grip stays fairly warm just from the heat of my hand. Its my left hand that goes numb from the cold.
