never mind the resemblance to a vaginal speculum or some other bizarre medical equipment, much more than a children's slide -- the concept is brilliant, though it doesn't eliminate the need for a stair.
Bloody Carpets Before beginning this DYI, make sure to use a surface (old rugs/shower carpets, etc.) that you don't mind getting paint on. Next, pour some red paint onto a paper plate and dip your feet in. Once your feet are lathered up, walk on whatever surface you are using and watch your crime scene bloody prints come to life.

Color-Changing Umbrella: The collapsible Color-Changing Umbrella transforms into a walking piece of art when used in the rain. The designers incorporated unique color-changing technology, so the splatter pattern on the Color-Changing Umbrella's exterior changes from white to bright shades of green, yellow, blue, pink, and orange when wet. As it dries, the umbrella's pattern returns to white.
