Another thanks to @missy and @rambo for extending the Blog Homework to Members. I am going to pick from past topics and see if I can make writing a regular thing.
I studied Product Design for 4 years, but never graduated. If you look at my portfolio patrickmuhs.squarespace.com you can see some things I have already invented, some I even built. Still I have that one idea that hasn't made its way to paper or shop...cold pillows!
I can't imagine I am the only one, but I sleep with 5 pillows and spend restless nights trading between which one my head rests upon. I won't complain about Souther California weather, it is ideal, but I like a relatively cool pillow. I place one or two against the wall to cool down, while burning up the one I lay on. I have considered putting pillow cases in ziplocs and keeping them in the fridge before bed, but that seems creepy.
My invention. A pillow with a space for a packet that can be placed in the freezer or microwave. This way everyone has the pillow they like. Room temperature, cool, or warm. Until then I will keep rotating between the five. Cheers...
