Dave's Gourmet, the maker of the well known, "Insanity Hot Sauce", has introduced a new bottle design that lets you adjust how hot you want your sauce.

The bottle has two sections, one containing mild sauce, the other containing hot sauce. By turning the cap, you can control how hot or mild you want it. Then you push the cap to mix and apply the sauce to your grub.
