Very often when we feel nervous or move intensively, our palms get wet and it's inconvenient to go on further actions by hands… This problem gets higher importance with sportsmen, esp. when they hold various sportive facilities in hand - for instance, players of table and lawn tennis, weight-lifters, and so on. Usually sportsmen use talc, but it's not very effective. So, my idea is to work out and use special device with chemical substance that, influencing sudoriferous glands, as well as nearby nerve endings, would stop sweating for certain period of time.
I am aware that there is certain surgical operations to stop sweating, but not all people would agree for operation, so, such device would be more practical!
