(Top Left): Design a product that allows toothpaste to easily be applied to a toothbrush and both tasks can be accomplished with one hand.
A toothbrush with toothpaste infused in the bristles that activates with water. Like a Mr. Clean pad for your mouth.
(Top Right) Design a product that enables an individual to open a pill bottle easily with one hand.

(Bottom Left) Design a product that efficiently cuts fingernails for someone with only one hand.
Nicknamed the “Nail Biter”, it is a mouthpiece with the clipping-end of a traditional set of nail clippers. When the user bites, the nail is clipped!
