You are a successful research scientist. You spend your life developing consumer friendly products which give people solutions to their everyday problems. So what is the killer problem to which you decide you must now devote your time and scientific skills?

Yes, you got in one. Variable temperature gloves:

These heated gloves make cold hands a thing of the past.

Battery-operated. Your fingers stay lovely and warm. Ideal for winter sports and outdoor work.

Just place a D-cell battery (available separately) in the little pocket on the back of each glove. You will then have ‘heating’ for up to 6 hours, warming up the area between the palm and fingers. Even when the thermometer is below zero, your gloves will remain at room temperature. Whether you’re skiing, walking or working outside, numb fingers will be a thing of the past.
The thermal lining is breathable.
Inside the gloves, you will be able to feel the soft Thinsulate® lining. Your hands won’t sweat so much, because of the breathable lining. The strong, water-repellent nylon outer material protects your gloves from damp. There is even enough room to carry your keys or lipstick in the battery pocket (batteries available separately). Two-years’ guarantee.
When others are still rubbing their freezing hands together, you can just switch on your ‘finger heating’.

However did we live without them?
