Have you ever looked at a covered pot and wondered if it's still hot? With this simple tool, you can visually check for yourself. Just print out this design with color-changing filament like on this Amazon link http://www.amazon.com/Gizmo-Dorks-1-75mm-Filament-Printers/dp/B00ITZO23O/ref=pd_bxgy_indust_img_y and insert some 3/4 inch magnets into the base. Place the indicator on top of the lid, and you'll instantly know if your pot is still scorching hot.
